Blocking for quarterback Don Meredith and playing with Peter Gent, Wilbur was an anti-hero, outspoken against the "racists elements" on the team and in the city.
[3] Part of the "Wild Rebel Bunch" contingency (along with Gent and Meredith), he infamously organized a group of Cowboys to be security guards at the Texas International Pop Festival.
Wilbur was a backup right guard for the Rams and played mostly on special teams under the auspices of hall of fame coach George Allen.
He was traded along with Jack Pardee, Maxie Baughan, Myron Pottios, Diron Talbert, Jeff Jordan and a 1971 fifth-round pick (124th overall–traded to Green Bay Packers for Boyd Dowler) from the Rams to the Washington Redskins for Marlin McKeever, first and third rounders in 1971 (10th and 63rd overall–Isiah Robertson and Dave Elmendorf respectively) and third, fourth, fifth, sixth and seventh rounders in 1972 (73rd, 99th, 125th, 151st and 177th overall–to New England Patriots, traded to Philadelphia Eagles for Joe Carollo, Bob Christiansen, Texas Southern defensive tackle Eddie Herbert and to New York Giants respectively) on January 28, 1971.
He became good friends with both McGovern and a young reporter, Hunter S. Thompson, who would later write Fear and Loathing on the Campaign Trail '72.
In 1974, just before the NFLPA lockout concerning binding arbitration for salary disputes, Wilbur left the NFL to play for the Hawaiians of the World Football League.
[11] Wilbur earned a master's degree in business administration from the University of California, Los Angeles while playing for the Dallas Cowboys.
As his years in the NFL wound down Wilbur played with the Hawaii Harlequins Rugby Football Club, and continued to enjoy the social aspects of the game long after hanging up his boots.
