I agree completely. In both football and basketball it's alarming how stubborn many coaches are and how poor they are at in-game adjustments. With this team, I don't know what to do besides giving Miller the ball on the block more. When your guards are all streaky shooters, can't run PnR and can't consistently beat someone off the dribble then you're going to be in trouble.
To be fair too, JC was really stubborn himself. We had A TON of ugly halfcourt offensive stretches during his tenure. We were dragged into plenty of slow-it-down games that had fans pulling our hair out watching our offensive execution. He was better than Ollie at exploiting mismatches, etc but Ollie is still a really young coach and will have to improve.
