NEW ORLEANS: After winning a record 405 games in 55 years as the head of the Grambling football program, Eddie Robinson has been ordered by the school to quit coaching. Doris Robinson confirmed that her 77-year-old husband, the winningest coach in college football history, has been asked by university president Ray Hicks to resign. Robinson's grandson, Air Force Capt. Mike Watkins, told ESPN that his grandfather was refusing to leave, saying he wanted to coach one more year for a "farewell tour." In his tenure at Grambling, Robinson has been regarded as one of greatest coaches and teachers in college football. He has sent more than 200 players to the NFL, including Doug Williams, the first black quarterback to start (and win) a Super Bowl. Robinson has had just seven losing seasons in his half century at Grambling, but two of them have come in the past two years, leaving many boosters feeling the need for a change. More damaging for Robinson: a recent series of off-the-field troubles. In April, the NCAA began investigating allegations of rules violations. Last month, four players were arrested and charged with dormitory rape of a 15-year-old girl after Grambling's homecoming victory against Alabama State.
