When you have all-new everything (coaches, schemes, many players, even the GM), especially 3 green QBs, winning a lot of games in year #1 is not a reasonable expectation.
I know many of us had great hopes for an instant turnaround, but you have to be realistic.
You can see the foundation being built this year, and another offseason (hopefully, offense-oriented FA and draft), Bills will be competitive next year.
