To this day, I do not understand how this situation could possibly unfold. Trailing the Tigers and driving for a game-winning drive, the Buffaloes scored the go-ahead touchdown on 5th down. Yes, 5th down. The Buffaloes spiked the ball to stop the clock, and the referees somehow overlooked the play. At the conclusion of the 1990 season, Colorado was ranked No. 1 in the AP Poll. Had it not been for the Buffaloes extra down, they would still have zero National Championships.
