You couldn't play him over those players
Really... That is the point. The #5 player in the country should have been starting!
Difficulty identifying talent and athletic ability... Dave Rose has the same issue this year, play Austin, Halford and Worthington or Play guys with a really good future. I would rather see some early season struggles with the talent than have the guys that "know the system" play.
My guess is that Rose will stick with the "tried and true" rationalizing that the other frontcourt players are freshman or sophs.
