Colorado’s rivalry with Oklahoma State is a history of improbable finishes: late rallies, bizarre plays and narrow escapes. The Buffs lead the series, but both teams have delivered unforgettable moments—including matching 11-10 wins, a last-second field goal to force a tie and a fake-field-goal touchdown in a windstorm.

By the Numbers
  • Colorado leads the series, 27-20, with 1 tie.
  • 15 games were decided by 7 points or fewer; Oklahoma State won 9.
  • Both teams have won an 11-10 game—one of just 19 such scores in more than 105,600 college football games.
  • In 1981, Colorado drove 92 yards in 1 minute, 22 seconds to win, 11-10.
Yes, But

The rivalry’s drama cuts both ways: Colorado has produced remarkable comebacks, but also surrendered a 20-point lead in a 1979 loss. Wind, disputed calls and unusual plays have often shaped the outcomes as much as conventional football.

Bottom Line

This series is defined less by dominance than by chaos: even a late lead—or a play that looks settled—has rarely guaranteed the result.
