JJ is a good coach IMO but if I was on walter's team, I would show him film of Rose's knee injury (thanks Thibs!) and the Cavs dropping game 1 against the Celts with Atkinson stating he wanted to save his TO's. Fix those two things and I think JJ has a chance to be an elite coach. He gets buyin from his players, his defense he concocted all high level stuff from him
