Michael Mark Pettine is an American football coach who is the assistant head coach for the Minnesota Vikings of the National Football League (NFL). He was the head coach of the Cleveland Browns from 2014 to 2015, and has also served as the defensive coordinator for the Buffalo Bills, New York Jets, and Green Bay Packers.

The 2015 season was the Cleveland Browns' 63rd in the National Football League, their 67th overall, and the second and final season under the head coach/general manager tandem of Mike Pettine and Ray Farmer. Both Pettine and Farmer were fired on January 3, 2016, after the team failed to improve on their 7–9 record from the previous season, going 3–13 season, tied with the Tennessee Titans for the worst record in the league. The Browns introduced new uniforms prior to the start of the season, updating the orange color to a darker hue, among other changes.
