What do you think?
To adress that issue a bit with some numbers:
With Nowitzki, Stojakovic and Terry on the court in 2011 (regular season and playoffs): 130.2 ORtg in 755 poss
With Stojakovic and Terry on the court: 110.3 ORtg in 539 poss.
The effect of spacing is more dictated by the efficiency the teammates are able to use that spacing than by role or teammates also being able to provide spacing. The overall effect for Nowitzki gets maximized by putting shooters around him, who can convert the open shots.
When I was looking for an example in which James didn't move well and destroyed any kind of good spacing, I was able to find it with the first hit. Game 4 of the finals, 4th quarter and 5 min to go. Wade has the ball while James is standing on the wings just watching Wade. What does happen? Wade is dribbling the ball and is forced to move to the wing, he is doubled by Kidd and Nowitzki, giving him no angle to pass the ball to Haslem. Stevenson is the primary defender on James, but because James is just standing there Stevenson can just move into the situation for a triple team on Wade while still being in arms reach to James. Stevenson is forcing the turnover leading to a inbound for the Mavericks.
Well, the pbp says that Wade had a turnover, I guess your EV will credit Wade with a turnover as well. But the real problem here was actually James. Him staying there on the wing and not moving gave the opportunity for the triple team on Wade. If Wade had passed the ball to James, the only chance would have been a catch&shoot for James over three defenders (Stevenson, Nowitzki and Kidd). Now, if James moves over to the corner instead, Stevenson either has to follow or Wade gets a better angle for a pass to James while James is basically open. When Stevenson follows, Wade has a chance to split the double and/or getting a better angle for a pass inside to Haslem. James not moving at all is reducing the possibility to score on that possession, while no on-ball metric will give him blame for that.
And you don't see Nowitzki standing on the strongside and doing nothing, he either is moving away to keep the spacing or he is setting screens for possible pick&roll or pick&pop. You think that is not a big issue, because I said in average the difference might be 3 pt per 100 possessions, but that is the difference between winning 41 games and 47 games in a 82 games season (assuming 70 poss per game for a player, similar to 36 min).
When you say that you are aware of the spacing effect, why haven't you mentioned it at least once in the comparison between James and Nowitzki? All I see are numbers which are based on on-ball action, while the really big difference between Nowitzki and James in the finals was the off-ball game. You are writing that Nowitzki was the "primary scoring hub/threat ... shooting the hell out of the ball", while presenting numbers that Nowitzki was actually not shooting at an awesome rate. That is implying that Nowitzki couldn't have played well or were actually having much of a bigger effect than James. Those numbers completely ignoring that Nowitzki took a couple of bailout shots. It also makes a difference whether someone is taking bad shots or is missing some good shots. Besides the 1st half of game 6 Nowitzki actually just missed rather good shots. He didn't force the issue while taking bad shots over multiple defenders, he played within the flow of the offense, which makes sure that his teammates are involved and getting opportunities. If Nowitzki would have been also shooting well, we would have seen a blowout in game 4 and game 6 would have been over after 3 quarters.
Regarding the free throws stuff I did NOT imply any sort of conspiracy theory at all. I simply assumed that you were quite satisified with those numbers presented by Hollinger, because they were a good fit for your argumentation. You didn't explicit search for them, you just didn't bother to check them, because it came in handy and was inline with your previous opinion. You are critical of opinions, because of possible biases, but you have not checked your own bias here before referring to Hollinger's numbers 3 times while it was pointed out twice before that those numbers are wrong. The same thing is happening again. You are accusing others of having a winning bias, completely ignoring the possibility that you are biased as well. I see a blind spot bias and confirmation bias in your posts here. You want that to see that Nowitzki and James aren't much apart, thus it is quite enough for you to look at on-ball stuff which is supporting your view, while completely ignoring the results during the time both were on the court. You want to assign the spacing effect as "conditional value" and you just assume (without anything to back that up) that this value would say nothing about how well a player played. That is ignorant on your part, because you just assume that James and Nowitzki had just the same effect with their off-ball game.
Maybe I'm looking too much into those things, which is likely caused by my soccer experience, a game in which moving without the ball is actually the main action for every player on the field, but even in basketball you have only 1 ball and 4 players on offense who don't have the ball in their hands. How those 4 players are moving without the ball and how they are distributing themselves on the court is crucial for the ball handler, because static not well distributed players will likely lead to double or even triple teams on the ball handler.
I also disagree that the effect is rather constant within a series, because each player has a good or bad day also in terms of moving without the ball. In soccer it is easier to see, because if a player is not moving well, he most times doesn't receive the ball at all, he is prone to being in a offside position or is just losing the ball rather quickly due to the defender being always close. In basketball such a bad day for a player will cause a player to be off by a meter or so, which doesn't look much. But the main effect is rather that the ball handler has less options. The player might look passive a bit, but it is not much seen when he has the ball in his hand.
Well, even in a case of a player being a better player with the ball, there can be a massive difference off-ball, which can cause that the guy with the better off-ball game is actually helping more than the other guy. And that off-ball game is actually a trait of the player.
So we've been talking about Spacing for 2 years. I appreciate your efforts in our discussions and it's certainly something I've grown to appreciate. I think it's widely underrated, although I think you overvalue it, or maybe just overvalue it in terms of Nowitzki.
With that said, I've asked you to quantify because I think it's a pretty interesting thing to try and put in perspective with other elements of the game. I also think, since we're getting into such nitty gritty (and hopefully people can bring this back around to Kevin Durant, Kevin Love, etc.) that it needs to be clarified that Opportunities Created can happen without the ball (if an extra defender is forced to react to something). Obviously, this doesn't happen a whole lot, because what we're talking about is holding a defender outside the paint because of the threat of shooting.
I don't really like your example with LeBron, because you are talking about "standing in a good place." That floor balance is basic stuff and/or dependent on coaching and scheme. I have a hard time believing in 90 offensive possessions, key players are standing next to other players with the ball, messing up the floor balance in that regard. So yes, I'd say your soccer background has your brain on overdrive here. Being off by a meter, if it were mucking up lanes, would be something a coach can simply point out in the first TO of the game. Again, I've never really seen this be a repetitive problem in this sense. It's like assuming a rebounder has a bad day because he was constantly out of position by a meter (for whatever reason).
The Spacing Effect, then, to me, is primarily about sucking defenders out with shooting threats (as I've written about and tried to examine). You say
The effect of spacing is more dictated by the efficiency the teammates are able to use that spacing than by role or teammates also being able to provide spacing. The overall effect for Nowitzki gets maximized by putting shooters around him, who can convert the open shots.
But that's like saying "Steve Nash's 'creation effect' is dictated by his teammates ability to hit open shots." Yes and No. Yes, in the obvious literal sense that if his teammates never hit shots, Nash could create all he wanted and it would be for naught. But no in the sense that, ESPECIALLY IN SMALL SAMPLES, we don't want to penalize players for their teammates missing open shots they should be making. I mean, no coach spreads the floor with open shooters so his best player can pass to them wide open and then says "crap that's a horrible shot for our team." Miami does this with Mario Chalmers and Shane Battier right now, and they would be better off if Steve Kerr and Steve Novak were shooting them, but I don't see what that has to do with LeBron James' ability to CREATE those open shots.
In Dirk's case, where Spacing is what helps his teammates, the DRIVING/CUTTING lanes are as important, if not more important, than the open shooters standing at the line. Are they not?
Consider, if we stick with the 2011 Mavs (RS + PS per BR):
Dirk alone: 2,023 pos 107 ORtg 53.3% eFG%
-- 0.24 3pA/pos, 0.18 FTA/pos
Dirk + Terry (no Peja): 3,285 pos 116 ORtg 52.8% eFG%
-- 0.20 3pA/pos, 0.34 FTA/pos
Dirk + Peja (no Terry): 383 pos 102 ORtg 53.0% eFG%
-- 0.28 3pA/pos, 0.14 FTA/pos
Dirk +Peja + Terry: 592 pos 131 ORtg 61.0% eFG%
-- 0.27 3pA/pos, 0.30 FTA/pos
You know who the two primary creators for the Mavs were last years? JJ Barea and Jason Terry (Kidd was 4th behind Dirk -- man I loathe assists). They loved the PnR. Dirk gets no credit in any metric (save the PM family) when his defender doesn't sag off as much to defend Terry's PnR, which will more quickly lead to a defensive breakdown, offensive rebounding, and open lanes at the rim. And as you can see, if we assume some faith in these raw numbers, when Terry was in the game the team shot free throws at roughly double the frequency. (!)
Then there's the other issue, which I just addressed, which is the actual conversion of the 3-point shots. If all the lineups hit 3's at the same rate of Dirk's alone lineup, the ORtg's would be:
Dirk alone: 107
Dirk + Terry: 117
Dirk + Peja: 107
Dirk + Peja + Terry: 121
Now, if we adjusted for the frequency of free throws (replace all the eFG attempts with FTA's at their given conversions, 78% FT%), the oRtg for the Dirk lineup would jump to 112 and the Dirk+Peja lineup up 6 points ot 108. That's how much getting to the line matters. So while the DIrk + Peja is taking more threes, are they suddenly taking three's that aren't open? Or is the lack of Terry (38% on 3's last year) just meaning those shots are taken by weaker shooters? And what would that have to do with how well Dirk Nowitzki played basketball?
Btw, I think 3pt/100 would be a huge Spacing Effect. 3pt/100 is like the difference between an average player and ~all-star. That's why I was so incredulous when you were floating this around, as if James has to make that up per game to equal Dirk (and relative to the league, Dirk was +2.1). Not saying it's impossible in this case, but I think that would be a big effect.
Finally, as MisterWestside said succinctly, I do feel a degree of cherry-picking here. I mean, do you want me to qualify every example I ever use with all the caveats and problems? And as I've said, defense would be an enormous place to start, although that's one of the areas I feel LBJ slacked on in last year's FInals, and I don't think that's what people are thinking about when they think "Dirk easily > LBJ 2011 Finals," do you?
