1991 Orange Bowl

Colorado compiled a 10–1–1 record in the regular season. In the opener at the Pigskin Classic in Anaheim, California, #8 Tennessee rallied from 21 points down and chose to kick an extra point for a 31–31 tie with less than three minutes remaining, and there was no additional scoring.[7] More than a month later, Colorado quarterback Charles Johnson[lower-alpha 1] scored a touchdown to beat Missouri 33–31, in a very controversial game in which Colorado was mistakenly given an extra down. The winning touchdown was scored on that play, and it was allowed to stand. That game is often referred to as the "5th down game." One reason for the Buffaloes No. 1 ranking was that they had the toughest schedule of any team. Another was quarterback Darian Hagan and half back Eric Bieniemy, who finished third in the Heisman Trophy voting. A victory seemed likely guarantee at least a share of the championship, but the Georgia Tech Yellow Jackets weren't far behind, second in both polls, and won the Citrus Bowl 45–21 over Nebraska earlier in the day to finish undefeated at 11–0–1.[8][9]

The Fighting Irish were 9–2; both losses occurred when they were first in the polls, and at home. The first was a 36–31 loss to 1–3 Stanford on October 6. The second was to Penn State on November 17, as Craig Fayak kicked a 34-yard field goal to hand the Irish a 24–21 loss,[10] which resulted in Notre Dame's No. 1 ranking falling to Colorado. Sophomore quarterback Rick Mirer passed for 1,824 yards and eight touchdowns, while Raghib Ismail accounted for 1,726 all-purpose yards, putting him on the All-American team as a wide receiver.

After a scoreless first quarter, Colorado's Jim Harper kicked a 22-yard field goal for the game's first points. A few minutes later, on 2nd and goal, tailback Ricky Watters plunged in from two yards to give the Fighting Irish the lead. But when Ronnie Bradford blocked Craig Hentrich's PAT attempt, the score remained 6–3. This cost Hentrich his 73 straight successful PAT attempts, a school record. Things would turn sour for the Buffaloes, however, as Hagan ruptured his tendon in his left knee just before the half, where the score remained the same.

This bowl is also remembered for a controversial finish. Ismail returned a punt 92 yards for a likely game-winning touchdown with 43 seconds left. This could have sealed the victory for Notre Dame and cost Colorado a share of the national championship. However, the touchdown was called back on a clipping penalty, and Colorado held on for the 10–9 victory.[4][6]

The 1991 win gave the Buffaloes their first and (to date) only national championship, shared with Georgia Tech.[11][12][13][14]
