I don't think Xs and Os are the main problem. Kids don't play hard for Ollie because of the positive reinforcement crap. Calhoun didn't put up with slacking, which college kids are more than willing to do if you let them. Calhoun's teams always fought harder for the rebound, lose ball, etc., and didn't want someone to score on them like their life depended on it. Ollie's don't. His temperament is not mean enough, and he's okay with sitting down on the sideline instead of up in the player's faces like Calhoun. He knows what Calhoun was like. That was his coach. He either can't or won't drop the player's coach cop out.
