Coaches Bennie Owen, Bud Wilkinson, and Barry Switzer have passed through the gameday tunnel for the Sooners, each on his way to the College Football Hall of Fame. Owen was the first highly successful coach at OU and was a major advocate of the forward pass, which at the turn of the century was not popular. The playing surface at Oklahoma's Gaylord Family Oklahoma Memorial Stadium is popularly known as Owen Field in honor of his long tenure and devotion to the university. Wilkinson left many imprints on the game, such as the 5-2 defense with five linemen and two linebackers; the perfection of the Split-T, an early option offense; three national championships; and his teams set the NCAA Division 1 record for consecutive wins at 47. The record of 47 straight wins is widely regarded as one of the great achievements in sports, and a streak that is unlikely to be broken (started October 10, 1953, vs. Texas and ended in 1957 with a loss to Notre Dame 7–0). Switzer won three national championships (the National Championship of 1975 is highly controversial; Arizona State went 12–0 that season while Oklahoma was 11–1) and forged arguably the fiercest rushing offense ever, the Oklahoma wishbone formation, throughout the 1970s and 1980s. Though the end of Switzer's tenure at Oklahoma was marked by controversy and poor player behavior, he is generally well regarded by both his past players and Sooner fans. During his 16 years as the Sooners' head coach, Switzer led his team to 12 conference championships and never lost more than two games in a row. His winning percentage of .837 stands as the fourth-highest in the history of 1-A football. Other Hall of Fame coaches whose tenure included stints at the University of Oklahoma are Lawrence "Biff" Jones and Jim Tatum.
