Ok, here is something provocative: can someone explain to me why TRob is a better prospect than Jae Crowder? Except, can you do it without mentioning TRob's measurements? Do it based on performance, in other words.
Both guys played the 4 in college at big programs, right?
Robinson is certainly a better rebounder. Every 40 minutes last season, he got 14.9 boards -- 4.7 more than Crowder. Big difference; big plus for his team.
Unfortunately, he turned the ball over 3.4 times in that same stretch to only 1.5 times for Crowder. That narrows the gap to +2.8 for Robinson. Still, that's a ball possession difference for his team. Helps them win.
Then again, Crowder stole the ball 3.1 times in those 40 minutes; Robinson only 1.4 times. Again, that narrows the gap. Still, Robinson had a better effect on ball possession. He gave his team 1.1 extra possessions over Crowder. Every possession helps, so good for him.
How about shooting? Well, Robinson scored 1 more point every 40 minutes than Robinson. But to get that extra point, he had to shoot the ball 1.7 more times and go to the line 2.1 more times. (There go those extra 1.1 possessions!)
Crowder's eFG% was .57; Robinson's .51. Crowder's TS% was .60 to .55 for Robinson.
Crowder had slightly more assists, slightly more blocks, and slightly fewer fouls than Robinson.
Robinson couldn't shoot the college 3-ball. Crowder did it reasonably well.
Again, someone tell me -- why is Robinson a better NBA prospect than Crowder? And if the answer is "because he rebounds more", then you also have to accept the evidence for Crowder that "he turns it over less, steals it more, shoots it better." All the numbers have to count, not just the ones you like. On the other hand, if the reason is "he's taller" then I'll happily repeat this post substituting Drew Gordon for Crowder.
It's a very important question, PIF. More broadly -- what role should the "eye test" play, if any, in evaluating a prospect? Should we be looking at all at what a guy looks like -- how he measures, his gait, etc -- or just what he actually produces.
The answer for me is actually more questions. The first is about the reliability and meaningfulness of the data. I think using stats to evaluate prospects is critically important; but the results are only meaningful if the data is good. For instance, assist numbers are notoriously subjective. Do NCAA scorekeepers inflate their own guys' blocks? Do they give 50/50 rebounds to their stars vs. their role guys?
Then there's a question of which metrics are truly important and/or predictive. I know there are dozens of stats that pro clubs have developed and track on a proprietary basis. Are they tracking these for the prospects? Do these stats play a 25% role of overall stat analysis of a player? 50? 75?
Getting back to the question, there may be other, less available stats, that say that RObinson is the far better (or far worse) prospect than Crowder. Maybe Marquette's official scorers juked Crowder's steal numbers. (The latter seems less likely and less overall impactful, but i'm still curious).
To the larger question, I do think that "stats" (without specifically defining which ones) are far more meaningful than the eye test. The eye test is just a piece of scouting though, certainly not all of it. Interviews with the prospect, his coaches, teammates. Psych profiles, medical exams, and watching game film to see how a guy was used and if he actually did what was asked of him -- those all strike me as important components too.
I think the draft is more of a science than an art, to be honest. It's just a question of using the right data and metrics. My $.02.
