PROVO, Utah — LaVell Edwards, who led BYU to national prominence with his dynamic passing offenses and became one of the most successful coaches in college football history, died Thursday. He was 86.

The school confirmed his death but disclosed no other details.

Edwards coached the Cougars for 29 seasons before retiring in 2000. He had a 257-101-3 record, the seventh-most wins in FBS history. His teams won or shared 19 conference titles and played in 22 bowl games. His 1984 team was voted national champion, and he was inducted into the College Football Hall of Fame in 2004.

Edwards became BYU’s head coach in 1972, taking over a program that had just 14 winning seasons in 49 years. BYU won 10 straight Western Athletic Conference titles from 1976 to 1985 and went to 17 consecutive bowls from 1978 to 1994.

Marc Wilson, Jim McMahon and Steve Young quarterbacked high-scoring offenses for Edwards from the 1970s into the ’80s. The Robbie Bosco-led 1984 team went 13-0 and was voted national champion, and quarterback Ty Detmer won the Heisman Trophy in 1990.

Edwards received national coach of the year awards in 1979 and ’84.

Edwards grew up in Orem, Utah, and was the eighth of 14 children. He was an all-conference lineman at Utah State before serving two years in the Army. He joined the BYU football staff in 1962 and was the team’s defensive coordinator when he was promoted to head coach.
