Turnovers has always been my biggest issue with Crean.
Even his best teams turn the ball over WAY too much. I get that he wants the team to push offense and , as a result, TO numbers will be higher. But I can't think of a single team - sans Carolina - that has won big consistently with high TO's, and the Heels rebound like nobody's business to compensate.
In the end, you can't give away possessions and expect long-term success. Hopefully his system will work well for him in Mizzou.
