Here's a quick primer as we enter Week 5:
Mississippi State (2-2, 0-2) at Georgia (2-2, 1-1), noon ET, Fox Sports Net: Both teams have won the games they were supposed to win to this point, but their fans were expecting a lot more. The winner of this battle of the Bulldogs has a chance to get on a little roll and turn things around. The loser could be in for a long season. Mississippi State avoided disaster last week by pulling out a win against Louisiana Tech in overtime.
No. 14 Texas A&M (2-1) at No. 18 Arkansas (3-1), noon ET, ESPN: The Hogs look to make it three in a row in the Southwest Classic against a Texas A&M team that will be playing in the SEC this time next season. Arkansas is hurting at defensive end. Jake Bequette hopes to be back this week after missing the past two games with a hamstring injury, and Tenarius Wright reportedly broke his forearm last week against Alabama.
Kentucky (2-2, 0-1) at No. 1 LSU (4-0, 1-0), 12:21 p.m. ET, SEC Network: With three wins against three Top 25 teams away from home in its pocket, LSU returns home to Tiger Stadium to face a Kentucky team that's reeling. The Tigers moved to No. 1 in the Associated Press poll on Sunday, while the Wildcats are trying to figure out how to generate any offense. They're coming off a 38-point home loss to Florida, and there's plenty of grumbling going on in the Bluegrass.
Buffalo (1-3) at Tennessee (2-1), 12:30 p.m. ET, CSS: After a week off, Tennessee returns to action in a stretch where it plays five of its first six games at home to open the season. The Vols shouldn't have any problem in this one, but then the preliminaries are over and we find out a lot more about Derek Dooley's second Tennessee team. The Vols get, in order, Georgia, LSU, Alabama and South Carolina. The good thing is that only the Alabama game is on the road.
Auburn (3-1, 1-0) at No. 10 South Carolina (4-0, 2-0), 3:30 p.m. ET, CBS: South Carolina coach Steve Spurrier apologized to the fans for what he called a "putrid" offensive performance in last week's 21-3 win against Vanderbilt. Quarterback Stephen Garcia threw four interceptions, but the Head Ball Coach is sticking with Garcia for the time being. Auburn's defense might be just what the doctor ordered for South Carolina's "putrid" offense, although coach Gene Chizik felt like his team improved on that side of the ball in the win against Florida Atlantic.
No. 3 Alabama (4-0, 1-0) at No. 12 Florida (4-0, 2-0), 8 p.m. ET, CBS: If only we're treated to a game as compelling as that SEC championship game showdown between these teams back in 2008. Alabama was supposed to be one of the top teams in the country this season and has certainly lived up to its billing. The Crimson Tide routed Arkansas last week. The Gators are also unbeaten and might be a little bit better than some people were expecting. It should be a lot of fun watching Alabama's rock-solid defense matched up against the speed of Chris Rainey and Jeff Demps.
Ole Miss (1-3) at Fresno State (2-2), 9:15 p.m. ET, ESPN2: It's not a pretty sight right now in Oxford, so maybe it's a good thing the Rebels are going all the way across the country this week to play a football game. Already saddled with three losses, Ole Miss needs a win in the worst way. Houston Nutt needs a win in the worst way, especially when you look at what's ahead. After a bye week, the Rebels face Alabama, Arkansas and Auburn in October.
