Gary Gaines, the coach depicted in the movie and book "Friday Night Lights", has resigned his position at Odessa Permian High School (Texas).He leaves after compiling a 69-28-1 record in eight years (1986-89, 2009-12) as Permian's head football coach. Gaines led the Panthers to a state championship in 1989, but boasted only a 23-21 mark with just one playoff victory since taking over the reins again in '09."We're going to give it to someone else and, hopefully, they can make more out of it than we did," Gaines said. "We came here to make some deep playoff runs and we weren't able to do that. That's what (Permian fans) expect, and I expect as well."Gaines would not say whether or not he was forced to resign, nor did he give any plans for what is next for him."It was just one of those things," he said. "I understand when programs don't improve sometimes the head coach has to bear that responsibility."Gaines was portrayed by actor Billy Bob Thornton in the 2004 film and was based off a book written by H.G. "Buzz" Bissinger. The author spent a year in the oil-producing town in 1988 in order to pen his book, which chronicled the attachment by a small community to its high school football team.From SI.com:After leading the Panthers to the state title more than 20 years ago, Gaines left Permian to become linebackers coach at Texas Tech. He left coaching in 2005 after five years at Abilene Christian to return to Odessa as the school district's athletic director. Two years later, he moved north to take a similar post in Lubbock. The once-vaunted Panthers have won six state titles but none since 1991. Before Gaines' return in 2009, the Permian program enjoyed something of a revival, making it to three regional finals the previous four seasons while compiling a 38-11 record under Darren Allman, a former Permian player and Gaines protege who left in 2009 to take the coaching job at Austin Westlake.Although Bissinger's best-selling book was heralded, it didn't go over so well with the folks in Odessa. The locals cited Bissinger's inclusion of the town's sociological woes, allegations of racism, and for exhibiting win-at-all costs mentaility, as reasons for their displeasure. NBC later aired a television series with the same name.Via Sports Illustrated.
