Tom Clements was hired In 1992 as quarterbacks coach for Notre Dame, where he served until 1995 under head coach Lou Holtz. After practicing law in 1996, Clements took his first NFL job, working as the quarterback coach for the New Orleans Saints from 1997 to 1999.
Clements would hold the same job in 2000 with the Kansas City Chiefs, and between 2001 and 2003 with the Pittsburgh Steelers; under Clements’s tutelage, the Chiefs’ Elvis Grbac (in 2000) and the Steelers’Kordell Stewart (in 2001) and Tommy Maddox (in 2002) each reached the Pro Bowl.
In 2004 and 2005 Clements served as offensive coordinator for the Buffalo Bills, but was released by the team after a front-office shakeup in which Marv Levy, his coach with the Chiefs in 1980, assumed the position of general manager and ultimately installed Dick Jauron as the team’s new head coach. Upon the hiring of Mike McCarthy to be the head coach of the Packers on January 11, 2006, the Packers parted ways with several assistant coaches, and McCarthy later interviewed NFL Europe head coach Steve Logan and Clements, settling on Clements on January 28, 2006.
During Clements time as the quarterbacks coach with the Green Bay Packers, he has worked with starting quarterbacks: Brett Favre, Aaron Rodgers, and Matt Flynn. In 2007, Favre statistically had one of his best seasons with the Green Bay Packers, taking them to the NFC Championship game. Clements is also credited for assisting in the development of one of the game's elite quarterbacks in Aaron Rodgers, as the only player in NFL history to throw for 4,000+ yards during his first two years as a starting quarterback in 2008 and 2009, and winning Super Bowl XLV and Super Bowl Most Valuable Player Award in Rodgers' third year as a starting quarterback in 2010. In Week 17 of the 2011 season, after the Packers went 14-1, head coach Mike McCarthy chose to deactivate Rodgers to keep him healthy for the playoffs and start backup quarterback, Matt Flynn, on January 1, 2012 at Lambeau Field vs. the Detroit Lions, Flynn's second start in his career. Throughout the game, Clements worked with Flynn on the sidelines, showing him what to look for in the photos from the previous offensive series. Flynn had a record-setting performance, throwing for 480 yards and 6 touchdowns, both single game records for the Green Bay Packers. On February 12, 2015 Tom Clements role was elevated to associate head coach with respective play-calling responsibilities.
