When he was OC under Wade early on I remember hearing him address the offense and thought he had a little fire. Haven't noticed that lately.
Sucks to come to that realization, but you're right...it is going to be a process.
He was barely a QB Coach when we made him a the HC in waiting.
I don't think he feels comfortable trying to correct with any unit other than offense, but he needs to at least make the effort to start interacting with them.
