Let's take a look at rotations by position. You can see a huge logjam already forming by the time we get to the guards and wings.
As much as I enjoy the thought of Cal running out a small ball lineup with four wings and Rabb at center, I doubt Cuonzo will want to take his big men off the court for too long. We saw what happened when Kravish had to play extended minutes at center last year, our team imploded on both sides of the court.
The big issue will be what we do on the wing.
