1. New England Patriots (12-4): The Patriots have made some big improvements in their secondary and with the additions of Revis and Browner. The big thing is that the Pats need to remain healthy on both sides of the ball, unlike they did last year, to make a deeper run in the post season.
2. Miami Dolphins (9-7): Beefing up the offensive line addressed one of the teams biggest needs. If their new additions work out for them, Tannehill having more time in the pocket, there will be a noticable improvement for this team in 2014.
3 New York Jets (8-8): With the addition of big name free agents on offense and a slew of young talent grooming on the roster, the Jets look to keep improving after a few sub par years. The biggest thing holding the team back is the pressure the team will have of who to start at QB for the long haul of the season.
4. Buffalo Bills (6-10): The Bills went all in to get Sammy Watkins, bringing a young talented wide receiver adding a weapon for EJ Manuel. Their defense isn't to shabby either, in a few years this may be an improved team however I still think they aren't ready yet to make a move past the 3 other teams in their division.
