OSU 20 ASU 17

You might recognize this as the score from the 1997 Rose Bowl when OSU defeated ASU by a score of 20-17 on a last minute (literally last minute - ASU got the ball back with 14 seconds on the clock) drive in the 4th quarter. It was on ESPN Classics today, and I caught the game with about 4 minutes left. Now, I was present at that game with many of my teammates (I think we all might have been screaming at Joe Germaine that David Boston was open - thank god he saw that too!) but can anyone explain to me why 11 years later it was still so stressful to watch, even though I WITNESSED the outcome?????
