The Bills don't exist in a vacuum. I'm not saying that we can't or won't beat the Phins (whose changes this offseason I largely consider a wash) and the Jets, but coming away with 3 wins out of those four games is going to be tougher than it was last year. Then there's the Pats**, Indy, Cincinnati, NYG, Cowgirls, and Chiefs, all of whom could easily end up with winning records this year.
I'm hoping for ten or eleven wins this year, but I can't say that either of those totals are the floor. Unless you mean floor for what's acceptable. Playoffs or bust, baby
