ESPN’s Football Power Index was dead-on last week with the LSU-Auburn game (50.5 percent), but Vanderbilt’s narrow escape only had a 41.4 percent chance at Western Kentucky. The schedule has narrowed for Week 5, but the number of toss-up games has not.

Will the East be decided in Athens? Will a team from the West suffer an upset?

Here comes Week 5 and what the numbers suggest should be a lopsided Saturday.

Alcorn State at Arkansas (99.5 percent): This lopsided matchup in Little Rock comes at an ideal bounce-back time for the Razorbacks. The Braves are 1-2 after the season opener was canceled. After they beat Alabama State, the Braves lost to Arkansas-Pine Bluff in three overtimes, and last week to Grambling State. With a game against Alabama on deck next, the Razorbacks will use this week to build confidence, and give some work to players down the depth chart.

Florida (74.7 percent) at Vanderbilt: Another bounce-back opportunity, this time to see if the Gators can put together a better second half than last week. That’s about the time, though, when Vanderbilt, conversely, woke up and turned on the momentum. While last year’s meeting was a narrow win for the Gators, 9-7, after Vanderbilt led in the fourth quarter, this one should be a showcase of Ralph Webb vs. the Gators’ front seven.

Louisiana-Monroe at Auburn (98.4 percent): The Tigers narrowly escaped the last meeting in 2012, 31-28. This one comes on homecoming and when the Warhawks are off a bye. They beat Southern to open the season, but have since lost to Oklahoma and Georgia Southern. Monroe should be a welcome opponent for Auburn to fix its red zone woes, and Rhett Lashlee adjusts to another week calling plays after the blood pressure ending against LSU. Whatever happens, the Warhawks will always have Alabama.

Tennessee (71.7 percent) at Georgia: While The Streak was all the talk last week, the Vols ended a five-game losing streak last year against Georgia with a bevy of points after Georgia built a 24-3 lead, but also lost Nick Chubb to injury. While this game was circled since at least the summer as a SEC East decider, things have shifted for each team in the past week. With control of the division again, this should reveal how the Vols handle being a favorite again, and how Georgia responds from the humbling loss at Ole Miss.

Texas A&M (88.6 percent) at South Carolina: Kenny Hill isn’t around anymore to bring back memories of the 2014 start and Heisman hype. But Trevor Knight showed last week that he’s capable of filling a highlight reel. The past two meetings have been shootouts, but this year’s Gamecock offense has yet to show any resemblance of that. A letdown could be possible on the road for the Aggies following a big win last week.

Kentucky at Alabama (97.9 percent): Another tuneup game for the Crimson Tide, though Bluegrass native Damien Harris’ knee injury, and potential absence, might take away from subplots when the game gets out of hand. UK has never won in Tuscaloosa and trails in the series 36-2-1. Conversely, Alabama has won its past 13 games against SEC East teams since its 2010 loss to South Carolina.

Memphis at Ole Miss (86 percent): There’s no doubt the Tigers have the Rebels’ attention following last year’s upset, not to mention the looming bye on the horizon. The defense certainly will be tested following Memphis’ 77-3 win over Bowling Green to move to 3-0. But the Rebels have another chance to squash the talk and one-liners of being a first-half team.

Missouri at LSU (80.9 percent): It’s Missouri’s first trip to Baton Rouge and their first SEC meeting. The programs last met in the 1978 Liberty Bowl. That would be a tall enough order on its own, but Barry Odom also has to face the emotions of a team following a coaching change. Though Missouri did beat Ole Miss twice when LSU interim coach Ed Orgeron was coaching the Rebels. It’s the first chance to see LSU’s revamped offense and its new wrinkles.
