Martin switched sides of the ball in 2012 and serves as offensive coordinator and quarterbacks coach after working with the Irish secondary from 2010-11.
Notre Dame averaged 189.38 yards rushing (2,462 yards in 13 games) and 222.7 yards passing (2,896). Only two Irish teams have ever achieved the 200-200 in both categories: the 1977 national champions averaged 231.9 rushing and 208.1 passing, and the 1970 team that finished No. 2 averaged 257.8 rushing and 252.7 passing.
Notre Dame was one of 26 teams in the FBS to average at least 189 yards on the ground and 200 yards the air.
Martin has been vital in the development of first-year quarterback Everett Golson. Golson started 11 games in 2012 and led the Irish to victories in all but one contest. Golson led Notre Dame to 10 straight wins to open his starting career, which was the second-most in school history. Bob Williams holds the school record as he guided Notre Dame to victories in his first 11 career starts. Golson was the first quarterback in school history to lead the Irish to road victories over top-10 foes in his first two respective road starts.
Prior to coming to Notre Dame, Martin was head coach at Grand Valley State for six seasons, following Kelly who served as the Lakers head coach from 1991-2003. While coaching the NCAA Division II school in Allendale, Mich., Martin directed the Lakers offense, continuing the same offensive system Kelly installed.
From 2004-09, the Grand Valley State offense led by Martin averaged 35.1 points per game, 427 total yards and 208 rushing yards per game.

Martin's offense produced a 1,000-yard rusher all six seasons he was in control of the Lakers offense. Four of the top 10 single-season rushing leaders and five of the 11 best single-season passing seasons happened from 2004-09.
