2. Doug Marrone (2013-2014)
Prior to Rex Ryan, the Buffalo Bills had hired Doug Marrone to be their head coach in 2013 after he was the head coach at Syracuse University from 2009 to 2012. The hire was a bit of a surprise at the time because while Syracuse had gotten better, it was far from being considered a top college program.
However, the move was seemingly a good one as the Buffalo Bills looked to be heading in the right direction under Doug Marrone. In his first season with the Bills, they would finish with a 6-10 record but finished the season winning two of their final three games.
In 2014, the Buffalo Bills continued to play well and even finished the season with a 9-7 record with Kyle Orton under center and being credited with seven of those wins. However, the Bills would come up short and miss the playoffs again.
Even with the success, Doug Marrone elected to step away after the season due to a clause in his contract that allowed him to do so if there was a change in ownership which resulted after the passing of Ralph Wilson.
Among the nine head coaches, Doug Marrone was the best coach the Buffalo Bills had with only Sean McDermott ranking ahead of him.
