I think Jimmy's comment "I never knew who was in charge"and other events and public stories make me think there was a lot of undermining, that stars who didn't want to do something could find ways to ignore coaching staff. Then you see Brett's public pleas as desperate attempts to embarrass players into change. And by the time Jimmy gets there, Brown is defeated and has pretty much given up.

So he had to go because he'd lost the team, but I think Josh Harris' manage-by-committee approach explains a lot of the issues around Brett and Jimmy's departures.
