Buster Ramsey became the first head coach of the Buffalo Bills in 1960, serving for two seasons before being fired by Bills owner Ralph Wilson after the 1961 season . In terms of tenure, Marv Levy has coached more games (182) and seasons (12) than any other coach in franchise history . He coached the Bills to four straight AFC Championships from 1990--1993, but failed to lead the team to a victory in the Super Bowl . One of Levy's predecessors, Lou Saban, who coached the team on two separate occasions, led the team to the victories in the AFL championship in 1964 and 1965 . Three Bills coaches--Saban, Levy and Chuck Knox--have been named coach of the year by at least one major news organization . Levy and Jim Ringo are the only Bills coaches to have been inducted into the Pro Football Hall of Fame . </P> <P> There have been six "interim" head coaches in Bills history . First, in 1968, head coach Joe Collier was fired two games into the season and replaced by Bills personnel director Harvey Johnson . Johnson did not serve as head coach the following season . Then, five games into the 1976 season, Saban unexpectedly resigned as head coach . He was replaced by Ringo, the team's offensive line coach . Ringo returned to coach the team again in the 1977 season . In October 1985, Kay Stephenson was fired and replaced by assistant head coach Hank Bullough .

Levy would then serve as Bills head coach for the next 12 seasons . In 2016, Anthony Lynn replaced Rex Ryan for the final game of the season . </P> <P> Following Levy's retirement, the Bills experienced limited success under a series of successive head coaches . Wade Phillips, the Bills defensive coordinator for the last three years under Levy, took over head coaching duties for the 1998 season . Phillips served as head coach for three seasons, making the playoffs in his first two (the second of which was the last time the Bills made the playoffs). After Phillips' departure following the 2000 season, Gregg Williams was named head coach . Williams served as coach for three seasons . At the end of the 2003 season, Williams' contract was not renewed . Mike Mularkey was named as the new head coach for the 2004 season, leading the Bills to their first winning season since 1999 . The Bills experienced less success under Mularkey during 2005, and Mularkey resigned as head coach at the completion of the 2005 season . The Bills then named Dick Jauron as their head coach for the 2006 season . Jauron was the first coach since Phillips' dismissal with prior head coaching experience, having previously served as head coach of the Chicago Bears and interim head coach of the Detroit Lions . Jauron coached the Bills to three consecutive 7--9 seasons before being fired on November 17, 2009, nine games into the 2009 season . On January 19, 2010, the Bills named Chan Gailey as their next head coach; Gailey was fired on December 31, 2012 . In January 2013, Doug Marrone was appointed .
