A better question is, where's Powe...and why is big baby getting more minutes than him.
because baby plays better team defense (specifically, rotating), and doc wants the second unit to be defense first.
You know, we hear this a lot, but is it true?
Points allowed per 100 possessions (team):
Powe on the court: 97.6
BBD on the court: 103.8
Points allowed per 48 minutes (team):
Powe on the court: 86.5
BBD on the court: 91.2
Net point differential:
Powe: +7.1 pts/48 minutes, +8.6 pts/100 possessions
BBD: +0.4 pts/48 minutes, +1.2 pts/100 possessions
Plus/minus:
Powe: +105, +.182/minute
BBD: +41, +0.068/minute (second worst on the team, behind Bill Walker)
Opponent's production (primary position):
Powe: .440 eFG%, 19.4 pts, 10.3 reb, 15.5 PER
BBD: .497 eFG%, 15.7 pts, 11.2 reb, 13.4 PER
Net production vs. opponent (primary position):
Powe: +.108 eFG%, +1.3 pts, +2.1 reb, +3.3 PER
BBD: -0.149 eFG%, -4.3 pts, -1.5 reb, -3.9 PER
====================================================
What do those stats tell us? They say that the team allows fewer points, and outscores their opponent by a significantly larger margin, when Leon is in the game. If BBD's team defensive is much better, that isn't shown statistically.
In terms of man to man defense, Leon allows a lower eFG% and gets more rebounds, but BBD allows fewer points, due to free throw attempts (+3.0 when Powe is guarding opponents) and more shot attempts.
So, there is no evidence that the team plays better defense with BBD in the game over Powe. Most importantly, though, there is absolutely *zero* evidence that the team plays better overall with BBD in there. The teams point differential, by any measure, is much better with Leon in the game.
