The 1950s saw the rise of yet more Dynasty (sports) and power programs. Oklahoma Sooners football, under coach Bud Wilkinson, won three national titles (1950, 1955, 1956) and all ten Big Eight Conference championships in the decade while building a record 47-game winning streak. Woody Hayes led Ohio State to two national titles, in 1954 and 1957, and won three Big Ten Conference football champions.  The Michigan State Spartans football were known as the "football factory" during the 1950s, where coaches Clarence Munn and Duffy Daugherty led the Spartans to two national titles and two Big Ten Conference football champions after joining the Big Ten Conference athletically in 1953.  Wilkinson and Hayes, along with Robert Neyland of Tennessee, oversaw a revival of the running game in the 1950s. Passing numbers dropped from an average of 18.9 attempts in 1951 to 13.6 attempts in 1955, while teams averaged just shy of 50 running plays per game. Nine out of ten Heisman Trophy winners in the 1950s were runners. Notre Dame, one of the biggest passing teams of the decade, saw a substantial decline in success; the 1950s were the only decade between 1920 and 1990 when the team did not win at least a share of the national title. Paul Hornung, Notre Dame quarterback, did, however, win the Heisman in 1956, becoming the only player from a losing team ever to do so.
