20 is fine. The extra 10 min/game he got from his soph to junior year didn't really do us much good. Obviously we had no choice, so if someone can step up and it gives Austin 20ish instead of 30ish, we should be in good shape. Means we actually have depth and not just the HOPE of depth.
Part of this whole PF/C rotation will also depend on Nielson as well. Still not sure what to expect from freshmen, but with Kaufusi, size is size and Nielson is still skinny. But like Mutu said, it will all pan out depending on who does what, how good each person is. It will decide where Aytes plays, where Nielson plays, how much Austin plays, etc.

It's always nice to have those first few easy preseason games. That will help us get all of these young guys some PT and see what they can do in a game situation. It will be fun watching each new guy progress.
