You mean the guy with the hightest +/- of anybody in the league (by far) Jayson Tatum? Or is there another Jayson Tatum that you are thinking of?

Yup, and this is partly what I’m talking about. The whole Celtics starting unit has gaudy +/- #s. If you’re referring to his OFF numbers which make it look like the Celtics offense just can’t possibly function without his 39% FG% and middling to below average play making then yeah I call BS.

He’s been Celtics 4th best player so far this year. To hear Celtics fans talk about it he’s this untradable all star, future MVP candidate and I just don’t see it. I don’t see that type of impact when I watch him play. He’s a good three point shooter and system defender. He doesn’t get to the rim or play make for others. He’s a one to two dribble player with a tendency to float in the offense. Obviously he has talent and I’m not saying he can’t one day be a great player with a lot of improvement but as the thread title says right now he’s someone who’s on court impact doesn’t match the reputation he has among NBA fans as this sure fire potential top 10 guy.

Do you even realize what your are saying? Nobody in the NBA right now affects his team as much as Tatum does. The Celtics have the best record in basketball, and Tatum is the guy who is doing the most to accomplish that. Yes, he had a bad (OK really bad) shooting game, any yet he still had a positive affect on the game. Is he perfect? Of course not. Can he improve aspects of his game? Of course. But right now, whenever he's on the floor, he is helping his team win more than anybody else in the league (again, by quite a wide margin). If you think that is over-rated, I don't know what to say. Tatum's reputation is growing quickly this season as not just an offensive player, but as an all-around player. He is one of the better defenders on the team, as well as one of their first choices on the offensive end. The Celtics are a much better team whenever Tatum is on the floor, and yet you seem to think that he is over-rated, or that he's not living up to his reputation. What does he have to do to impress you? Does he need to score 40 points a game? Does he need to average a triple double? Right now he's doing exactly what Boston needs him to do, and he's doing it at an incredible rate (better than any other name you can throw out there). Not only is Tatum living up to his reputation, but he's playing much better than it.

His box numbers have been incredible, but his impact just isn't there.


No worries.

Life is great. Basketball gods blessed the Mavs. And Clowney wrecked the 49ers - did you see the fear in JimmyG's eyes? That was so beautiful. Let me be very frank, if I was rooting for most other teams (and I have plenty on top of my head), I'd be trading my whole franchise away for Doncic. We went from being just about the most boring team in the league to having fun every other night.

So while I actually enjoy criticism or different points of view, in this particular case, it's actually just symbolic of how far ahead of time he is --- guy is not 21 yet. Scoring 28.3 ppg on 61 TS%. 10.3 rbs, 9.1 assists. If someone told us that he'd be averaging this in year 2... we'd be laughing at them.

What I infer from your post is that you must be committing a mortal sin --- you have not watched the Mavs (Doncic) play much this year. I'd find it hard to believe that if you saw a guy have good numbers and make the right plays, that you then would look at +/- and somehow think he hasn't made that much impact. You grant him incredible numbers. So if the incredible numbers don't translate into the +/- column, "what is he doing wrong?" What is he doing that is hindering team success? What are others doing that is "making up for Doncic's lack of impact"? It's actually hard to ask him to better his numbers (it's possible, but if this stat line is beyond what most optimists would expect in year 2).

Is he preventing the team from being better? Should he shoot (even) better? Play off the ball more? A case has been made for that, but of course, this is more about coaching and having other guys run the team while he is on the floor. Let Brunson run the team on his own since he has the best +/- through 10 games despite shooting below 50%ts? Should he ask Tim Hardaway Jr how to better his game since, by the same data, he has amazing +/-?

Here's what one sees when watching him play this year, he makes good decisions most of the time. Dare I say he is an elite decision maker already? Because if you are on the floor with him... you can be sure he can find you, at any time, anywhere. He is extremely unselfish, looks to pass often, other times he looks to score when he feels that the team needs a spark and he needs to take over. Managing those moments, managing all the plays (guy literally does ALL the heavy lifting on offense) is quite complex for a 20 year old, and he has done superbly given the context. The way he reads and instinctively reacts is impressive since he is operating "at his own speed" and against some athletic freaks. So you get my idea... you see a guy playing well, being a team player --- not some guy who is 'selfishly' piling up numbers. How can you then somehow put the blame of the +/- at his doorstep? You can't. And I doubt you would if you were a Mavs fan or just watched the team play. You would look at other reasons and not at the guy that is having a goat season for a 20yo.

Since his numbers are good. We have to really dig deep for problems, I guess most would be:

--- shot selection, some low percentage shots (it's actually not that many now, but they stick out when taken, especially because he shows that he can get better shots with apparent ease)
--- some careless turnovers
--- some defensive lapses, guys cutting behind him while he is looking away, giving up some uncontested layups
--- occasionally there were complaints about passiveness in trying to score, early in the season (comical to say "early", when we only played 10 games, but think of the Blazers game)

Here's the thing though, you can see his improvement from last year and during this young season. This is his current shot chart

ImageImage

Lives at the basket now and scores at an elite level there, shooting better than Lebron there probably. His FT% jumped up incredibly from last season. Some actually advocate that he should shoot more from midrange since he gets the space, but he's actually pretty much eliminated mid-range shots from his game thus far. At times he takes some wild shots because he must get really bored of manipulating defenders and getting them on his back as he either takes a floater or lobs it up for someone else.

He has toyed with at least 3 teams this year. Meaning... he played at half pace... and put up some of the ridiculous numbers you see on his game logs. I invite you to watch games vs Wizards, vs Cavs, vs Grizzlies. You will know.

You mention the rookie year. Can't ignore the Mavs make major moves that impacted the team. A visualization, raw +/- since it's the thing brought up, +7 before major moves. -150 the rest of the way. Rough idea: Before: 55 ts% (29.3 usg%), after 52.3 ts% (33.5 usg%). From (20 - 7 - 5.6) to (22 - 9.9 - 7.2). Essentially, the team had a structure before the trades, then blown up (and thankfully they did that) and it was just a mess the rest of the way. So his numbers are definitely skewed by that.

The basketball post trades was abysmal. That includes Doncic's own basketball - it wasn't very pretty to watch at all. Talent was there, but it was just bad basketball. So I would only be concerned with the +/- data if he was playing inefficiently (like last year post trade). That is not the case at all (as the individual numbers immediately tell you)... so it's really more of a case where you look at the guy and feel cool with what he is doing, so then you look at "other reasons".

It's 10 games. He has had 2 bad games out of 10. Look at his numbers. He was -17 in Boston. A top team in the league. Boston fans can chime in here and tell us what they witnessed... they are or were what 7-1, 8-1?... and Doncic was the best player on the floor (please allow me to say this Kemba). He played against Smart the whole game and some other guy doubling him. Not Wannamaker, the Williams guy or whoever like the bench dudes did.

Blitzed by double teams, made the right play pretty much every time. And still found a way to score on his own because he just had to. Willed the team back and take a lead in the 4th quarter. Killed by Kemba in the end. He was -12 in the 4Q despite playing well.

Here's some of the Boston double teams:

He was -17 in Denver - where he actually played terribly and the Mavs bench had a surreal game. So in one game he played great, -17. In another he played badly, -17. Same number. Totally different story.

The +/- data that you are using in your OP tells us this:

Tim Hardaway Jr is the Mavs just most impactful player this year. He is rocking a +17.6.

Reality: he is an abomination. Jacks shots up like there's no tomorrow. Pylon on defense. Shooting just 37-percent from the field, 32-percent from deep. These plays actually reflect the player on offense and defense:

I have monitored the +/- all year and it's also intriguing how Brunson (who I love) actually has the best +/- and he has played below his level [Brunson is #3 in the league when on the court, +14.4!]. The only guy who actually has a +/- that matches "the eye test" is Delon Wright who should play more minutes --- you can just see his impact with defensive disruption, timely drives.

The Mavericks don't have a set lineup. They've had 8 different starting lineups if not mistaken. And at the moment it's actually difficult to know exactly what to expect each night, except for you know who.

I don't put too much stock on the "off" numbers since at this point Carlisle has proven that he can have a midget PG, you and some random rim-rolling big and crush other teams benches.

If you're ever bored, go through this topic: viewtopic.php?f=12&t=1717833&start=1120 I dumped some videos in there over time. Hey, they may not translate to the +/-, but they're basketball porn. And I know you love it. So just watch and have fun.

No that’s not what his plus-minus and on-off implies. Yes, it’s likely that Tatum is doing little things that don’t show up in the box score, and so he’s outperforming the BPM estimate of his impact. Tatum is clearly a good player. But saying that because he has the league’s best plus-minus numbers (haven’t looked into that myself though) he’s helping his team win more than any other player...that’s ridiculous. All it’s saying is that when Tatum is on the floor the Celtics perform very, very well. Over these small samples there’s not enough data and it’s probable that Tatum has played in some great lineups and not played significant minutes with the less impactful players on his team compared to his peers on the Celtics and other top players around the league. But do you honestly believe that if you took away Tatum it would hurt the Celtics more than if you took away Giannis from Milwaukee, LeBron from LA, or Harden from Houston?

Maybe you haven't watched a lot of Celtic's games this year. Yes, Tatum does start the game with the other starters, but he spends more than half his time on the floor with at least 2 or 3 bench players during most of the game (Stevens likes to use starters and bench players together a lot). What do you think +/- numbers even mean? It's a reflection of how a player impacts a game. Tatum has the highest +/- numbers of any other player in the league right now (by more than 15 points). That means that whenever he is on the floor, his team plays better than when he's not on the floor. There is no other way of interpreting this. Tatum helps his team win games more than any other player on his team, more than any other player in the league right now. Whether that's through scoring points, or stopping the other team from scoring points (or in his case both), he is one of the main reasons why Boston has the best record in the league. Again, he's not perfect. There are many things he needs to do to become better, but to say that he's not living up to his reputation (which implies that he's over-rated) just makes ZERO sense. I am in no way implying that he's the best player in the game. He's not even the best player on his team, but he does affect winning more than any other player. kind of hard to say that a player like that is not living up to his reputation.

It’s really easy to see which minutes the Mavs have been winning. It’s the minutes when Luka and KP especially are not on the court. You might not think those other players are good, but they are out scoring the other team like crazy and that is what has lead to a 6-4 record.


I assume that Luka’s 28/10/9 against starters helps winning a little or we should assume that Mavs would have be 9:1 or 10:0 without Luka?


No, we don't have to strawman. But we can easily recognize which minutes the Mavericks are winning and which minutes they are losing.


Yeah, but that's kind of the point. The Mavs bench is winning because they are a great reserve squad and are playing against other benches. Whereas Doncic has to start with players who would be fine in a bench role but are severely undermatched against the opposing team’s starters.

For example, let’s look at their five-man lineup with the second most minutes: Jalen Brunson - Delon Wright - Tim Hardaway Jr. - Justin Jackson - Dwight Powell. They have played 24 minutes so far with a Net Rating of +36.0, which is obviously great. But would they really be able to sustain even a positive net rating if they were consistently matched against starter line-ups? Most likely not.

The Mavs have a plethora of versatile fillers / role players who are excellent in certain areas, so it is possible to field many creative situational line-ups which can work very well in limited minutes despite their lack of individual brilliance. But all these line-ups would fall apart if there wasn't a big anchoring presence in Doncic to whom can bridge towards.

The Mavs are winning for both reasons, because the bench is great and because Doncic is able to hold water with the starters. It just isn't correct to assume that Doncic has no help and these lineups are falling apart when Doncic isn't on the court. They are +13 per100 without him anchoring the lineups.

Kawhi actually has a great rep on defense from casual fans but from from diehard fans not so much because he was coasting a bit in regular season last year. This year I think Kawhi is back at playing DPOTY level defense:

- 1 block a game for how much time he spends on the wing that's impressive

- 4.3 DBPM

- 98 defensive rating

- despite missing 2 games, still has clippers as a top 10 ranked defensive team with very poor defenders on the roster such as Patterson, Shamet, Lou, Harrell

- NBA.com has Kawhi as a net rating of 13.1

Man, the strawmans in this thread are incredible - the Luka fanboy factor is strong. The OP didn't say Luka is a bad player who should be sitting in favor of someone else, he just brought up the fact that Luka has a negative +/- and negative on/off this year, which is worth examining. Some of the Mavs' fans explanations - collinearity with KP and early season small sample size - give good hints that Luka's impact isn't as poor as those numbers may indicate.

I'd also add that Luka's defense does looks it still has room for improvement. That was pretty noticeable during the last game vs. the Celtics, but to be fair I've only watched one other game from him this season.

I believe that +/- stats should be discarded as serious at the moment, when a player with 1/18 shooting has gotten + 16. ;) In the same game a player with 34 points, 9 assists and 7 rebounds, 67 TS%, only 1 TO, has gotten -17. OP’s model says that Tatum had incredible game and Luka disastrous.

He correlated impact with +/- and on/off without showing us that this is how impact is defined.

Saying that he has a negative +/- and negative on/off and then saying that it means his impact doesn't match his reputation is a strawman considering not everyone agrees that this is what impact means. He didn't just "brought a fact". Which is the problem.

How about win shares? Doncic is 6th. Why does that not show impact?

- 1 block a game for how much time he spends on the wing that's impressive

- 4.3 DBPM

- 98 defensive rating

- despite missing 2 games, still has clippers as a top 10 ranked defensive team with very poor defenders on the roster such as Patterson, Shamet, Lou, Harrell

- NBA.com has Kawhi as a net rating of 13.1


That's because Leonard is the best player in the game fam


Exactly. How many guys have averaged 26\9\6 with a net rating of 13.1


I know Embiid hasn't, that's for sure!

I believe that +/- stats should be discarded as serious at the moment, when a player with 1/18 shooting has gotten + 16. ;) In the same game a player with 34 points, 9 assists and 7 rebounds, 67 TS%, only 1 TO, has gotten -17. OP’s model says that Tatum had incredible game and Luka disastrous.

You basically proved my point, as this is the kind of strawman I am talking about. No one in this thread argued that single-game +/- means anything.

He correlated impact with +/- and on/off without showing us that this is how impact is defined.

Saying that he has a negative +/- and negative on/off and then saying that it means his impact doesn't match his reputation is a strawman considering not everyone agrees that this is what impact means. He didn't just "brought a fact". Which is the problem.

How about win shares? Doncic is 6th. Why does that not show impact?

First of all, it seems like you don't know what a strawman is. The OP was arguing that looking at +/- in conjunction with on/off may give us insights on impact. Maybe you disagree with that, but that doesn't mean he was arguing with any strawman. IMO trying to draw insights like that on this particular season, this early in the season, with plus/minus, on/off or any impact stats is a bit treacherous as those stats tend to be noisy as it is. To his credit the OP tried to connect it to last season as well, which is a larger sample size. Either way, the PIPM stat I provided earlier alongside some Mavs' explanations in this thread give a clearer explanation of why Luka's impact is likely much better than the +/- and on/off stats may indicate.

It's also wise to realize that the OP favors impact stats much more than traditional or advanced boxscore stats, so he's approaching the topic from a certain angle.

That certainly has to play a part, but even among Mavs starters he was 2nd worst last season and is 2nd worst this season. And it’s not like Carlisle uses 5 man substitutions to completely pit the starters against the bench.


So far this season the issue seems to be KP. Zach Lowe addressed this briefly in his ten things column on Friday: https://www.espn.com/nba/story/_/id/28021786/ten-nba-things-like-including-luka-doncic-trickery

The thing to consider is the Mavs roster has been a dumpster fire since Doncic got there with the exception of their bench. When you look at the players Luka has most commonly played with it becomes a lot easier to see why his on/off has been so bad.


Then why do those same unimpressive players have better on/offs than Luka? That's why I feel like the rotation argument will be lacking no matter how you cut it. I'd be more willing to accept that 10 games just isn't a worthy sample size, and that last year he was still getting acclimated to the league.
I think that's it, the sample size.
But if the trend continues it will be worth deep diving into it.

Don’t you find movement of +/- a bit erratic, if a 1/18 player gets 33 points swing in his favor in 1 game? Theoretically can that happen in every single game, but even if that happened only few times in first 10 games, is result from OP’s model compromised. Sure after 82 games results might be more realistic, but he was too impatient and triggered the gun way to early. And there will be always question mark about representative value of this data. There is just to much of the noise in +/-.

He didn't say "may" which makes a difference. The thread title says "A player whose impact doesn't match his reputation."
And the conclusion is "His box numbers have been incredible, but his impact just isn't there." It MAY indeed give us an insight on impact, but he took it for granted before he proved it. I think it's a problem.

I know what a strawman is. OP took the argument that Doncic has a great impact and used the argument that he didn't based on +/- and on/off, when most people who thinks Doncic has a great impact don't think that those two things necessarily define impact. Maybe they do, maybe they don't. I'm certainly not convinced as it is incredibly dependant on who you are playing with, who you are playing against and who's on the bench. All outside factors.

"The typical straw man argument creates the illusion of having completely refuted or defeated an opponent's proposition through the covert replacement of it with a different proposition." I would say that defining impact with +/- and on/off is a different proposition.

I don't like being told that I don't know what someone is when I feel that the other person doesn't know what it is.

The Mavs have been a bench led team for awhile now, and no surprise looking at the names in their starting lineup, KP isn't ready to contribute yet. It's still early but the numbers that attempt to isolate a player from their lineups (APM and their ilk) are quite kind to Luka.
I bought a boat.

I believe people should look at Luka’s +/- very carefully. I will rather watch his live games.
