I have been on board with this idea for almost 20 years!
I thinK buffalo vs Cleveland already has the sprinklings of a really good rivalry with yearly matchups, fan travelling, all the QBs going down last year with some contraversy, Pettine, etc...
The Dolphins make me feel nothing. I hate the Jets, but only because I hate all NYC teams. I have been a fan since about '85 and I really cant remember too many key Jets/Bills moments/games (if any). I dislike the Patriots, because I hate Belichik and Brady, the previous cheating and am jealous of the success... but I hate to say it, Bob Kraft is a class act and almost all Patriots fans I have encountered are classy too.
I think the NFL is long overdue to shake up the alignment a bit. Its been almost 15 years with nothing changed.
