When Shanahan's father Mike was hired by the Redskins, Kyle brought LaFleur to Washington to coach the quarterbacks. A primary responsibility of LaFleur's for the 2012 season was to mentor rookie quarterbacks Robert Griffin III and Kirk Cousins, whom LaFleur was particularly fond of.
On February 5, 2015, LaFleur was hired to be the Quarterbacks coach for the Atlanta Falcons working under offensive coordinator Kyle Shanahan, whom he previously had worked under when with the Washington Redskins. Matt's brother, Mike, was the offensive assistant with the Falcons as well.
In the 2016 season, LaFleur and the Falcons reached Super Bowl LI, where they faced the New England Patriots on February 5, 2017. In the Super Bowl, the Falcons fell in a 34–28 overtime defeat.
On January 30, 2018, LaFleur left his position with the Rams to take the same position with the Tennessee Titans. Joining new head coach Mike Vrabel, LaFleur now has the opportunity of calling the plays for the Titans, essentially being a promotion from his former position as offensive coordinator with the Rams. Personal life
LaFleur's younger brother, Mike LaFleur, is the wide receivers coach/passing game specialist for the San Francisco 49ers. LaFleur, a native of Mt. Pleasant, Michigan, was a three-year starting quarterback at Saginaw Valley State where he guided his team to the Division II playoffs each season.
