In 1980, as an assistant under head coach John Wilkins at Permian, Gaines helped lead the team to the Texas 5A state championship.
Gaines, though, will be most remembered for how he was portrayed in "Friday Night Lights" -- the book/movie about the journey of the 1988 Permian High School football team that marched toward a championship.
Gaines enjoyed tremendous success during his stint at Permian ... leading the team to a perfect 16-0 season and the 1989 5A state championship.
"Friday Night Lights" received an ESPY for "Best Sports Movie" in 2005 and won "Movie of the Year" that same year. Billy Bob Thorntonfamously portrayed Gaines in the flick.
