Okay, so I feel like instigating a little conflict. Why? Because, that's why. Hate on Baynes if you want, but the reality is that when he's in the game, opponent FG% is 17% below average inside the restricted area. Overall, teams are averaging 0.993 points per possession (PPP) when he's on the court, vs. 1.094 PPP with Drummond on court. Put bluntly, the team is a better defensive team with Baynes on the court. But wait, isn't the knock on him that he doesn't rebound the ball? Yes. But the real question is: is the team suffering for it? Not really - when Drummond is subbed out for Baynes, other players pick up the slack:Morris' rebound rate goes from 5.9% to 9.3%Harris' goes from 7.6 to 8.7%Leuer's goes from 9.2% to 16.8In fact, the team rebounds 50% of total opportunities with Drummond on court, and 50.8% of opponents' misses with Baynes on the court, which implies that Drummond getting all the boards may actually have a negative impact on the team (perhaps it leads to other players not fighting as hard for them and the Pistons consequently losing out on opportunities). More likely, though, such a small difference in rates is really more or less an indication that there isn't any difference between the two players at all. Could his rebounding be better? Maybe, and simply comparing his results to Drummond's doesn't paint the full picture - especially since the two play with different teammates. But it's one more piece of evidence in favor of that old coaching adage that rebounding is a team effort, and the reality is that Baynes' defensive percentages over Drummond more than make up for his rebounding "deficiencies" (Baynes' fourth quarter defensive numbers are sick: opponents shoot splits of -33/-20/-15.5 from 0-6 ft/0-10 ft/15+ ft). But what about on offense? The team averages 1.094 PPP with Drummond on the court but only 1.045 with Baynes on the court. That certainly indicates that Baynes is having a negative impact offensively. Then again, Baynes plays with different players. It might help to determine how different players play with him on the court. When I run the numbers, though, Drummond clearly helps almost all players' EFG% (Ish, Thrilliard, Stajo, and 1 game of RJ have better EFG's). So I now have no doubt that Drummond is superior offensively. So it's a little of thunder and lightning - Baynes is far better defensively, Drummond is far better offensively. But between the two, the Pistons have a higher PPP margin with Baynes on the court than they do with Drummond, because Drummond is a worse defensive player than Baynes is an offensive player. So take that for what it's worth.
