Of course the Stoerner fumble is clearly number one due to the clear impact on the National Championship.
The 1990 season was the most frustrating year of Tennessee football for me simply because I felt that the 1990 team was one of the most talented teams in Tennessee history. The 91 and 92 NFL drafts included 18 Tennessee players with three players taken in the top 12 in 1991. That year, 1990, we had two plays that seemed to be season/history turns.
Tennessee is tied 6 - 6 with Alabama and going for a game winning field goal with less than one minute to go. We fumble the snap and the ball is recovered about 20 yards back. Alabama runs one play, loses yardage, then kicks game winning field goal.
Tennessee is mounting an epic comeback against Notre Dame. We recover an onside kick, drive to tie with less than a minute to go and Andy Kelly throws an interception in the end zone.
