If it gets the best players on the court and brings in wins, unhappiness is fine by me; any team has unhappy players, or players who wish they got more time. With the injury history under Norm, everyone's gonna get a chance to shine!
I think Rob will get time - there are only 4 forward/ centers on the roster, after all, unless Brownlee plays down low (and according to his local paper, he's working on his perimeter game (!)), and Quincy can play more as a senior or earn playing time in practice - didn't we hear that Paris earned his time by outplaying Larry Wright (or at least playing defense)?
It's true that there are only so many minutes to go around, but every college team plays with 200 player-minutes. If managed right, it's a welcome problem to have. And if someone chooses to leave because of playing time, good luck to them and we can (hopefully) get another viable player who won't be a freshman in 2011.
