Georgia. Because it was the most unpredictable thing ever. They were supposed to have the East on lockdown from the opening kickoff, then we go into their house and show them who's boss.
The Florida win was real exciting, but after watching the rest of Zook's season, the whole thing feels less impressive than it did at the time. Beating a team that was superior in every way (UGA) feels a lot better. But I have to say UF @ Tenn and the Rose Bowl had, hands down, the two most exciting field goals of 2004.
