In honor of Florida Gulf Coast's stunning run in the NCAA basketball tournament, I started thinking back to some of the biggest SEC football upsets of my lifetime.

The mid- to late-1970s is about as far back as I go, but I’ve gone back and picked out some of the more memorable ones over the past 30 or 35 years.

These are all SEC vs. SEC matchups, and I’ll rank the top 5 as well as five more that just missed the cut. I’ll come back later Thursday with a few more, including some upsets in non-conference and bowl games.

Here goes:

1. Mississippi State 6, Alabama 3 (1980): The No. 1-ranked Crimson Tide had won 28 straight (and an SEC-record 27 straight conference games) and were heavily favored against the unranked Bulldogs. But Mississippi State played suffocating defense that day in Jackson, Miss., and snuffed out a late Alabama drive. The Crimson Tide had moved to the Bulldogs’ 4, but were out of timeouts. Alabama quarterback Don Jacobs took the snap and started down the line of scrimmage to the right side. Mississippi State’s Tyrone Keys shot through and tackled Jacobs, forcing a fumble that Billy Jackson recovered to seal one of the greatest wins in Mississippi State history. Alabama’s wishbone attack, which had been averaging more than 300 yards per game, mustered just 116 rushing yards against the Mississippi State defense. The Crimson Tide lost four fumbles in the game. And in a classy gesture afterward, Alabama coach Paul “Bear” Bryant visited the Mississippi State locker room to congratulate the Bulldogs on the win.

2. LSU 17, Alabama 13 (1993): The No. 5 Crimson Tide had gone 31 straight games without a loss and were coming off an unbeaten national championship season. Inexplicably, they lost at home to an unranked LSU team that had lost five of its first seven games that season and finished 5-6. The Tigers were a 24-point underdog that day and in the midst of their fifth straight losing season. Alabama starting quarterback Jay Barker was out with an injured shoulder, and the Tide -- using three different quarterbacks -- threw four second-half interceptions. Coach Gene Stallings finally went to David Palmer at quarterback late in the third quarter, and “The Deuce” directed the Tide on a pair of scoring drives. But LSU held on for the win, and Stallings said afterward that he waited too long to go to Palmer, who was normally a receiver.

3. Ole Miss 31, Florida 30 (2008): The Rebels would go on to have a very good season, but ventured into the Swamp that day as a 22-point underdog with losses to Wake Forest and Vanderbilt during the first month of the season. Nobody gave them a chance. The Gators were ranked No. 4 and riding high with Tim Tebow running the show. But the Rebels stuffed him on fourth-and-short late to pull off an improbable road win. The game is best remembered for Tebow’s emotional speech afterward, when he promised that nobody would work harder than him and his teammates the rest of the season. The Gators would go on to win their next 22 games in a row, including the 2008 national championship.

4. Auburn 23, Georgia 23 (1994): Even though it wasn’t a loss, it sure felt like one for No. 3 Auburn, which had its 20-game winning streak under Terry Bowden stopped. The Bulldogs were unranked and had lost at home to Vanderbilt a few weeks earlier. But they rallied from 14 points down on the road thanks to a couple of Eric Zeier touchdown passes and survived a missed 44-yard field goal attempt by Auburn’s Matt Hawkins with 13 seconds to play. That was Ray Goff’s next-to-last season at Georgia, which finished 6-4-1 and didn’t play in a bowl game. It didn’t get any better the next week for Auburn. The Tigers, who were on NCAA probation, lost to Alabama.

5. Alabama 9, Tennessee 6 (1990): The Vols were ranked No. 3, coming off a 45-3 demolition of Florida and very much in the national title picture. Alabama had started the season with three straight losses, the first season with Stallings as coach, and was unranked entering the game. But Alabama’s defense stole the show that day before a stunned crowd at Neyland Stadium and shut down Tennessee’s high-powered offense. With the game tied at 6-6, the Vols were able to get into a position for a 50-yard field goal attempt with 1:35 to play, but Alabama’s Stacy Harrison blocked it. The ball scooted more than 20 yards the other way to the Tennessee 37, and Phillip Doyle won it for the Crimson Tide with a 47-yard field goal on the last play of the game to make it five in a row against the Vols.

The five that just missed the cut:

Ole Miss 22, Alabama 12 (1988): Yep, it's the infamous brick through the window game. An irate fan tossed a brick through the office window of Alabama coach Bill Curry after the Rebels stunned the No. 12-ranked Tide in Tuscaloosa. It was Ole Miss’ first win ever against Alabama in the state of Alabama, and spoiled the dedication of the new Paul “Bear” Bryant Museum. Alabama didn’t complete a pass that day.

Alabama 17, Auburn 15 (1984): The Alabama fans refer to it as the “Wrong Way Bo” Iron Bowl. Auburn coach Pat Dye elected to go for it on fourth-and-goal from the 1 late in the fourth quarter, but Bo Jackson went the wrong way on the play. Alabama’s Rory Turner forced Brent Fullwood out of bounds on the sweep, and the Tide held on to beat the No. 11-ranked Tigers and knock them out of the Sugar Bowl. It was a sweet end for Alabama to its first losing season since 1957.

LSU 31, Tennessee 20 (2001): The No. 2-ranked Vols were coming off a huge win at Florida and poised to go to the Rose Bowl to face Miami for the national championship, but backup quarterback Matt Mauck rallied the Tigers in the second half after filling in for the injured Rohan Davey and gave Nick Saban his first of two SEC titles in Baton Rouge.

Georgia 24, Florida 3 (1985): The Bulldogs romped past the No. 1-ranked Gators with freshman running back backs Keith Henderson and Tim Worley both rushing for 100 yards. It was the only game Florida lost all season. The Gators were ineligible to play in the Sugar Bowl because of NCAA sanctions, but finished No. 5 in the final Associated Press poll.

Arkansas 25, Tennessee 24 (1992): The Vols were ranked No. 4 and had already beaten Florida, Georgia and LSU. The Hogs opened that season, their first in the SEC, by losing to The Citadel, resulting in the firing of Jack Crowe as coach. Joe Kines took over as interim coach and guided a 1-4 Arkansas team to a stunning comeback win against the heavily favored Vols in Knoxville. Todd Wright won it for the Hogs with a 41-yard field goal with two seconds left.
