Indiana might still be undefeated, but the Hoosiers have to take down Ohio State as a 13.5-point dog in Week 13 to keep it that way. I pick a side in my Week 13 college football picks below.

As the regular season winds down and conference title matchups begin to take shape, the nation's top teams must do whatever they can to avoid a late-season slip-up.

That includes Ohio State -- which hosts undefeated Indiana -- and Alabama, which heads to Norman to take on Oklahoma. Those matchups highlight my Week 13 college football picks below.

Technically a Top 5 matchup that lacks the feel of one when you lay eyes on this spread. Still, the narrative surrounding Indiana has gone a bit too far; Ohio State wins, but the Hoosiers cover.

Even if the Rebels miss the SEC title game, they have a shot at the Playoff if they look the part down the stretch. Such can't be said about Florida.

Simply put, Penn State has to dominate the rest of the way should it plan to host a Playoff game. The Nittany Lions are 2-0 ATS since losing to the Buckeyes and have exceeded expectations by an average of 12.5 points.

Eight straight covers will turn to nine as the Buffs get one step closer to claiming a Big 12 title. They're simply playing too well to fade them now.

I'm not ready to completely write off BYU after its first loss. This Cougars defense will still be the best unit on the field.

This has more to do with the Wildcats -- who played at Tennessee three weeks ago and lost by 10 as a 17.5-point dog -- than it does about the Longhorns. Texas wins 30-13.

Despite an impressive 9-0 record, Army has bitten off more than it can chew with this game. Notre Dame rolls.

When you combine the state of Oklahoma's offense with the state of Alabama's defense, you get a Crimson Tide-sized blowout.
