Between 1954-56, the Sooners reeled off a still-unmatched streak of 47 consecutive wins, with the '56 season serving as true tour de force. In OU's 10 games that season they allowed just two teams to score touchdowns, and only surrendered four touchdowns over the course of the entire season. In addition to pitching six shutouts, the Sooners failed to score more than 40 points just three times. Where these dudes for real? They started the season with 36-0, 66-0, and 45-0 beat downs of UNC, Kansas State, and Texas, respectively. OU also torched little brothers, Oklahoma State, to the tune of 53-0 in the final game of the regular season.
Disclaimer: While the Sooners were crowned national champions, they made no bowl appearance due to a then Big 7 conference rule that no team could make consecutive bowl game appearances. We doubt it would've made any difference.
