As mau said, it was far more 'mental' than physical with Steve. It's amazing how much 'quicker' a guy gets when he becomes more instinctive and knows what to do.
Transferring is the best thing that he could do imo, and not necessarily to get different coaching (although that may help), but to get that year off to develop he desperately needs. I think that will be the greatest factor in Steve's development. And there's nothing UCONN could have done at this point to make that happen, there's no way they'd red shirt a rising Jr, especially with such holes and uncertainties in the middle.
Steve needed to red shirt his freshman year, but the coaches didn't do it, for whatever reason. They let him down there.
