1990 national champion in the Associated Press's final poll. The 1990 Colorado Buffaloes football team represented the University of Colorado Boulder as a member of the Big Eight Conference during the 1990 NCAA Division I-A football season. The Buffaloes offense scored 338 points while the defense allowed 160 points. Led by head coach Bill McCartney, Colorado defeated Notre Dame 10–9 in the 1991 Orange Bowl to conclude the season. Despite the infamous Fifth Down Game controversy against a 4–7 Missouri Tigers football team, Colorado was selected national champions by AP, Berryman, Billingsley, DeVold, FB News, Football Research, FW, Matthews, NFF, Sporting News, and USA/CNN, and co-champion by both FACT and NCF -all NCAA-designated major selectors. Georgia Tech took the UPI Coaches poll title, with both Washington and Miami receiving national titles from other selectors. Georgia Tech finished the season undefeated (with its record only blemished by a tie), and subsequently split the national championship with Colorado. The victory in the Orange Bowl was Colorado's first bowl win in nineteen years. Wiki link
