Not much to Brady. He's still a top 5 all time QB. Moss may lose a little exposure but overall he'll stay fairly solid with the possibility of movement either way depending on what happens to him in the offseason as he's a free agent. They had potential to jump more. Instead they will just plateau for now.
Don't think Moss is going anywhere unless all he cares about is the green. Judging by what Moss and Brady have said - they will be a package deal - at least according to two writers that I always read and have very good insight on the NFL
