John Butler, who helped build Buffalo's Super Bowl teams of the 1990s before becoming general manager of the San Diego Chargers, died of lung cancer Friday at the age of 56.
Butler was instrumental in building the Chargers back into something the fans of San Diego can be proud of.
Chargers coach Marty Schottenheimer, quarterback Drew Brees, former Bills coach Marv Levy, and former Buffalo quarterback Jim Kelly all attended the services.
"John Butler was beloved for all reasons _ his tremendous competence in the field,'' Levy told WICD-TV in Champaign, Ill. "But he was a friend of everybody in the organization.
"He was a man to be admired and emulated."
Before his NFL football career, Butler spent four years in the Marines and saw active duty in Vietnam. At the University of Illinois, he played one season on the offensive line before a knee injury cut short his playing career.
A memorial service will be held in San Diego this spring, his wife Alice said.
