Literally none of the "experts" is picking the Bills to win the AFC East and most of the ones I've heard are picking the Bills to miss the playoffs entirely. Usually, the explanation is that the the Phins and Jets got better, but the Bills did not, which of course is laughable.
I love it. I think this is exactly where we want to be entering the season--underrated, with a chip on our shoulder. As I've pointed out in other threads though, despite the experts' negativity, Vegas still likes the Bills to win the AFCE, and to beat the Jests Monday night...so there's that.
