What to watch today in college football

2:30 p.m., Ch. 4

What's at stake: It's a battle of the Southeastern Conference's two remaining unbeaten teams. The winner will have the inside track to a berth in the SEC Championship Game, presumably with a playoff shot on the line.

The skinny: The Aggies lead the SEC and rank seventh nationally in rushing offense behind freshman RB Trayveon Williams and QB Trevor Knight. The Crimson Tide has the nation's stingiest run defense, allowing just 63.9 yards per game.

The line: Alabama by 17½

11 a.m., ESPN

What's at stake: Quite possibly the Big Ten West title. The winner of the past two meetings between these teams has won the division — and Wisconsin is likely out of the race with a loss. For all its struggles, Iowa is just a half-game behind unbeaten Nebraska in the West.

The skinny: Wisconsin has won 37 of its past 50 Big Ten games — and each of those 13 losses came by seven points or fewer.

7 p.m., Ch. 5

What's at stake: Ohio State can improve to 35-1 in regular-season conference games under coach Urban Meyer and can take another step toward the Big Ten championship game with a win. The Nittany Lions are still looking for a marquee win during James Franklin's tenure. He's 0-7 against Ohio State, Michigan and Michigan State, and the Nittany Lions are 0-9 against top-five teams in the past decade.

The skinny: Ohio State QB J.T. Barrett's completion percentage is down to 59 percent over the past three games and he's thrown an interception in each one, but he's rushed for 275 yards and three touchdowns in those games.

Line: Ohio State by 20

5 p.m., ESPN

The skinny: Arkansas is playing its third straight game against a Top 25 opponent and has faced five ranked teams in its first eight games for the first time.

Line: Auburn by 10½

8 p.m., ESPN

What's at stake: LSU, which has next week off before hosting unbeaten Alabama on Nov. 5, can move into the thick of the SEC West title race with a victory but would fade to long-shot status with a loss. Ole Miss cannot afford another divisional loss if the Rebels hope to retain remote hopes of sneaking back into the divisional race.

The skinny: Mississippi QB Chad Kelly, who has a TD pass in 19 straight games, leads the SEC with 343.7 total yards per game and 308.2 yards passing per game.
