Isn't rebounding a part of defense?
Agree. If Rak rebounds like he did the last 4-5 minutes of the Miami game from here on out, Keita's only going to be in there when Rak needs a blow or is in foul trouble. Christmas really doesn't need to do anything else to justify his presence on the floor over Keita's. The tricky bit is getting him to play that well every game. The last two games make me hopeful, though.
