The browns have a good defense, a potential franchise player with Johnny, a good receiving core with Gordon and Cameron and their oline is nasty. Hardly one of the worst teams.
Titans are a mess.
Bills have a solid defense, Manual is looking better game by game. Cj Spiller is a Madden beast not to mention their better than average receivers.
Giants are intriguing. They look better on paper than they do in real life which equals better Madden ratings.
The Bucs have a lot of upside players. Glennon and Martin on offense and on defense they have some good young players.
I wouldn't have put the Vikes on the list myself either. I would have went titans since they have a lack of playmakers all around.
