Have we seen anyone really do that since Singler? Tre and Grayson had plenty to gain by returning, regarding NBA draft stock.
I'd argue Grayson could've left after his sophomore season. I think Grayson could be the last star player we see stay all four years. If we got Matthew back for a 3rd year it would certainly buck the current trend. Also, it would make that team next season not one to trifle with. Singler coming back for his senior year shocked me. I thought for sure he was gone after we cut the nets down in 2010.
