I agree, the D is most certainly over rated.
You play what your schedule gives you- I think it's unfortunate the AFC East is basically horrible now. It's a lot like when the Patriots had their run...no competition.
Playoff time will be interesting. I'd actually be concerned facing teams like Denver & Pittsburgh because of the veteran coach angle with Payton & Tomlin. The Bills are more talented, sure, but I'm concerned. We would match up better with Baltimore, it would probably be a game like today with little D.
They'll end up a 2 or 3 seed, but IMHO the AFC is a lot more wide open. We really want the SB but it's going to be tougher than ever to get there.
