I think another year of chemistry and health will put us in the top 5 defensively. Stop trying to convulate facts. We were 30th when Casey started and depending on the stat you want to argue anywhere between 7th and 10th now. 20 spots of improvement with a developing centre and starting two second year players and not one single elite man defender on the entire team.
Casey gets the credit for that. PERIOD
You can still question some of his play calls and rotations or whatever because there may or may not be validity there. But at least give the man credit for the things he is good at
