Done by division just a little on each team, if anything.
AFC East
Buffalo Bills: Hey they added TO that should help right? Probably yes. TO is known for being very productive his first year at every team he has been with. That being said I thik the situation is much different in Buffalo. Also if you thought he dropped a lot of passes in Dallas just waitt ill he plays in wintery mess that is Buffalo. Can't really say how the team will do But they couldn't beat the Pats even wthout Brady last season.
NY Jets: The Jets improved last year that was for sure but in the Favre did what he does best, throw INT's. The end result was Mangini getting canned. Now they have new coach, Rex Ryan is it? They also have at least two nobody's for QB's. that unless end up being surprisingly good this year aren't likely to be good enough to compete. Since the coach is not from the exsisting system I think that will hinder the team as well. They would be lucky to finish with the previous years record I think.
Miami Dolphins: Easily the surprise team of the league last season I honestly cannot predict how they will do this year. My feeling though is not as good as last season because I feel alot of thier success was based on the surprise of no one thinking they would be challenge.
NE Patriots: Brady went down in the frst game of the season and the whole league changed, especillay with the division. I think the Pats are already a better team than last year and maybe even the previous year. The success of his team and really how the other teams do I think rides a lot how well Brady can play and how long it takes him to get back into the groove if he can.
