Here's my rankings, based on (objective as possible) entertainment value:
8th - 2001 Miami 37, Neb 14--Neb probably didn't belong there. Not contest from the start.
7th - 2004 - I can't recall what happened
6th - 1999 - FSU 46, Vtech 29, boring game
5th - 1998 Tenn 23, FSU 16, good game, but eh.
4th - 2003 LSU 21, OU 14, exciting to the finish. Dropped (tipped) pass in the endzone would have sent it to OT
3rd - 2000 OU 13, FSU 2, Noone expected OU to even compete. Great win for the big underdog
2nd - 2005 UT 41, USC 38, spectacular plays on both sides of the ball. Thrilling finish.
1st - 2002 OSU 31, Miami 24 2OT, 2 OTs, the PI call in the endzone. Fantastic game that the supposedly overmatched Bucknuts pull off.
I could be persuaded to flip 1 and 2--both great games.
