I think he has done well for a bright eyed young guy. He does need someone hardened by old age and treachery above him. Brandon should not be that guy. Now Mr. P is filling that role until he finds someone he is comfortable with paying to do it for him. The fringe players will be gone once Mr. P gets his ducks in row.
Brandon may stay in a business capacity. Whaley will probably stay if Mr. P likes him. It seems to me that Marrone and Whaley had a disconnect. Maybe a personality clash. It's too bad because although he may have been a dick, I think Marrone did change the culture of the team. Sometimes some body
needs to be an a hole. Sometime people perform better when the are mad. It can take some to the next level i.e. Jerry Hughes, Robert Woods.
I think Marrone needs an enemy. Unfortunately I think it was Whaley. Do your job Dougie and get us a good Coach and somehow make The Schwarz happy to stay put.
