Beyond strictly looking at wins and losses, DVOA by Football Outsiders gives a clear picture of team performance.

The following Infographic shows the past 10 years of DVOA rankings (2008-2017) for the Buffalo Bills.

The Bills finally ended their playoff drought in 2017, sneaking into the playoffs with a -57 point differential and their worst team in DVOA over the past four seasons. 

Doug Marrone began the turnaround with Sean McDermott taking the baton after a brief Rex Ryan interlude. Where the Bills go from here is unclear as they parted ways with Tyrod Taylor and drafted Josh Allen in the first round.
