Brady's pocket mobility declined some this season, not drastically, but some. His arm is totally fine, no measurable drop-off there. His biggest problem I think was he didn't really want to play for Tampa Bay this season, got contractually locked into it, and then quickly realized his concerns were very justified. It affected him mentally (probably along with the off-field issues as well) and you could see it in his attitude and demeanor. At this point in his career he has no patience left, which is a problem, and if he can't find a situation that he's extremely enthusiastic about then he probably should just head to the broadcast booth.
