Michael Charles Leach (born March 9, 1961) is an American college football coach who is currently the head coach at Mississippi State University. He was previously the head coach at Texas Tech University and Washington State University where he ranks as the third winningest coach in school history.
Leach is known for building potent offenses, directing passing-oriented teams that have broken school and NCAA records at Valdosta State and Kentucky where he was offensive coordinator under Hal Mumme, developing their "Air Raid Offense", at Oklahoma under head coach Bob Stoops, and Texas Tech, where he became head coach in 2000. Leach's spread offense relies heavily on passing and he has seen several of his quarterbacks post NCAA records. At Kentucky he tutored prospect Tim Couch into a No. 1 NFL draft pick. At Oklahoma, Josh Heupel became an NFL draft pick following a year under Leach's tutelage.
