We're in the final stretch of the college football season, and Week 13 features some great matchups. Betting on over-under point totals can be tricky, so sit back and let us do the research for you.

Here are our top over-under bets for the weekend.

*Odds subject to change

Ohio State Buckeyes vs. Indiana Hoosiers UNDER 52.5 total points (-100) – BetMGM

Ohio State has perhaps the best defense in the nation, ranking second in total yards allowed and first in points allowed. Indiana has a solid offense, but hasn't faced elite competition this year. The Buckeyes are averaging 29 points per game and should get around that mark against the Hoosiers, but it's hard to envision Indiana getting to 20 or more points.

Notre Dame Fighting Irish vs. Army Black Knights UNDER 44.5 total points (-110) – DraftKings

Army is a popular upset favorite this week, but I'm not sold. While the Black Knights are having a great season, they've faced a very easy schedule. Notre Dame is on a roll right now and have one of the best defenses in the nation.

Army's passing attack is very limited, and the Fighting Irish have an elite secondary. I can't see the Black Knights putting up a lot of points in this game, and I expect Notre Dame to be more efficient than explosive on offense.

Ole Miss Rebels vs. Florida Gators OVER 55.5 total points (-110) – Caesars Sportsbook

Ole Miss has one of the best offenses in college football, ranking second in total yards and fourth in points per game. The Rebels should feast against a Florida defense that ranks 101st in the nation in yards allowed per game at 400.4.

While I think that Ole Miss will win comfortably, Florida should be able to put up some points as it tries to keep up. The Gators have averaged 28 points over their last four games, and should be plenty motivated during their last home game and fighting to be bowl eligible.
