I can go one better. Team fires the coaching staff after a 5-11 season, hires on a new HC with no previous HC experience. He picks their QB of the future in the first round of the draft though many considered him a reach. That HC and QB tandem goes to the playoffs 5 years in a row, with at least 1 win each year in the playoffs, capped off by a SB win.
I could see the Bills going like either the '49ers or Ravens. You bring in a good HC like both these teams have and you'll have success.
And my prediction this year is a 10-6 record, win wild card game, lose divisional.
