The 1984 Alabama-Auburn Game
17 - 15 Alabama
Trailing 17–15 late in the game, Auburn had 4th-and-goal from the one-yard line. Opting to go for it, Auburn called a pitch to running back Brent Fullwood. Running back Bo Jackson, who was supposed to block for Fullwood, ran the wrong direction, allowing the Alabama defense to easily push Fullwood out of bounds short of the goal line to seal the victory.
