The Georgia-Florida rivalry dates back 99 years, with the 100th meeting between the bitter rivals coming Saturday (3:30 p.m. ET, CBS) at TIAA Bank Field in Jacksonville.

Georgia has been installed as a 22-point favorite, the largest point spread in this series since 1995, when the Gators opened as 19.5-point favorites despite the game being contested at Sanford Stadium in Athens because of renovations to Jacksonville’s Gator Bowl. Florida was also a 19-point favorite in 2001, the largest spread in a game held in Jacksonville — until now.

Needless to say, the smart people in Vegas aren’t giving Billy Napier and the Gators much of a chance Saturday against Kirby Smart’s No. 1 Georgia team.

That’s likely sound logic, except that the Cocktail Party is one of those games where lines-makers are frequently wrong.

Like the Iron Bowl, which has seen underdogs cover the spread (8) or win outright (6) many times since 2000, the Georgia vs. Florida game has seen its fair share of upsets this century, with underdogs winning outright on 6 occasions and covering on 5 others.

Could an upset happen again on Saturday?

It’s tough to see how, given the matchups. But then again, strange things tend to happen on the banks of the St. Johns River.

Here’s a Saturday Down South list of 5 Cocktail Party upsets that defied logic — and featured wins by double-digit underdogs:

1966: Georgia 27, No. 7 Florida 10

The Gators, led by All-American quarterback Steve Spurrier, needed a win over Georgia to claim a share of the SEC championship for the 1st time in program history. Once again, Florida came into Jacksonville after an emotional win over Auburn, which included Spurrier kicking a game-winning field goal.

The Bulldogs, led by All-American defensive tackle Bill Stanfill, flustered and flummoxed Spurrier all afternoon, forcing 3 interceptions and routing the Gators by 17 points. Stanfill, who added offseason muscle by holding pigs for his dad to butcher and castrate, famously said after the game that holding the pigs “sure did remind me an awful lot of sacking Steve Spurrier.”

Spurrier won the Heisman Trophy, but Florida did not win the SEC championship, and Spurrier never forgot the heartbreak in Jacksonville. He would use it as fuel for the remainder of his career, emphasizing beating Georgia at both Florida and South Carolina as a head coach.

1985: No. 17 Georgia 24, No. 1 Florida 3

The Bulldogs were playing well when they arrived in Jacksonville, having demolished Kentucky and Tulane in their prior 2 games. Tackling No. 1 Florida, which was coming off an impressive win over Bo Jackson’s Auburn team and playing with the No. 1 ranking for the 1st time in school history, was going to be a more difficult task. Or so most lines-makers thought, installing the Gators as double-digit favorites. Florida entered the game with the nation’s top-ranked defense, having limited Jackson to under 75 yards rushing.

Vince Dooley and Georgia weren’t intimidated, though, and both Tim Worley and Keith Henderson eclipsed 100 yards rushing as the Bulldogs snuffed out Florida’s dreams of an undefeated season and rolled the Gators 24-3.

Florida did shake off the loss and win the SEC in 1985 — though the Gators were ineligible to claim the trophy after a league vote — but UF wouldn’t be ranked No. 1 again until the Steve Spurrier Era. Georgia, meanwhile, won for the first time against a No. 1 opponent in the illustrious Vince Dooley Era. 

1997: No. 14 Georgia 37, No. 6 Florida 17

The lone win for Georgia in Spurrier’s tenure as Florida’s head ball coach came on a rainy, humid November day in 1997. The Gators, the defending national champions, had an outstanding defense ranked in the top 10 nationally entering the game.

Their offense, a work in progress after the graduation of Heisman winner Danny Wuerffel and the departure of All-American wide receivers Reidel Anthony and Ike Hilliard to the NFL, was still potent, having piled up over 400 yards in a 24-10 win at Auburn to build momentum heading into Jacksonville.

But the Gators defense, so dominant in the Auburn win, wilted against the Georgia run game, allowing Robert Edwards to grind out 124 yards and a then-school record 4 rushing touchdowns in dominating Florida, a double-digit favorite.

Spurrier used 3 quarterbacks in the game, trying to find an answer for an offense that threw 4 interceptions. None came, and after the loss Spurrier summed up the afternoon and the end of Florida’s 7-game winning streak over Georgia in a memorable manner:

“Georgia beat us in every aspect. The Bulldogs outcoached us and outplayed us. Florida has no excuses; Georgia is better than the Gators. They just beat us.”

2002: Florida 20, No. 4 Georgia 13

Georgia was a perfect 8-0 under Mark Richt, led by a defense ranked in the top 5 in the country and a 2-headed, playmaking monster at quarterback in precision passer David Greene and electric playmaker DJ Shockley. Greene had moved the Georgia offense well heading into Florida Week, but with 4 minutes to play in a nip-and-tuck 1st half, Richt elected to give Shockley a possession.

Shockley threw a pass out near the boundary, which was intercepted by Florida safety Guss Scott, who ran it back for a touchdown and gave the Gators, playing Georgia without Steve Spurrier as their head coach for the first time in over a decade, a halftime lead. Two Billy Bennett field goals staked Georgia to a narrow 13-12 lead in the 4th quarter, but it was Florida’s All-American quarterback, Rex Grossman, who would be the hero.

Playing on a sprained knee, Grossman, who threw for 339 yards on a tremendous 36-of-45 passing in the Florida win, led the Gators on a 10-play, 89-yard game-winning touchdown drive that culminated with a 10-yard TD strike to tight end Ben Troupe, a Georgia native.

The loss sparked another famous call from legendary Georgia announcer Larry Munson, who proclaimed as time expired: “They’ve broken our hearts, again, these Florida Gators. They’ve pulled our hearts out of our chest and stomped on them and our national championship dreams with their boots and they don’t care one bit. They’ll sing and cheer all night, and we’re left with broken hearts and the longest drive home tomorrow.”

Florida’s win was 1 of 2 for a double-digit underdog in the rivalry this century.

2014: Florida 38, No. 9 Georgia 20

The Gators arrived in Jacksonville at 3-3 and most of Florida’s fans expected this to be the last game as head coach for the embattled Will Muschamp. A Georgia alum, Muschamp had never experienced a win over Florida as a player and was 0-3 against his alma mater as a head coach. Florida, 13-point underdogs, changed all of that in one afternoon.

On a cold day with winds blustering off the St. Johns at 25-to-30 miles per hour, the Gators stuck with the running game, attempting only 6 passes but bullying Georgia at the point of attack. Florida ran for 418 yards, with both Kelvin Taylor and Matt Jones approaching 200 yards rushing on their own, in walloping Richt and the Dawgs in a game that wasn’t nearly as close as the score.

Florida radio announcer Mick Hubert’s calls of both a 2nd-quarter fake field goal, which saw walk-on holder Michael McNeeley run the ball 21 yards for a game-tying touchdown, and a long, ice-the-game touchdown run by Taylor, were classic Hubert, as he exalted Muschamp’s guts and splattered in a handful of his trademark “Oh Mys.”

This would be Muschamp’s lone win over Georgia, as he was dismissed as Florida’s head coach less than a month after the win.
