Most races around college football lack clarity, but Week 13 is destined to provide some long-awaited answers.

In the Big 12, BYU travels to Arizona State for a critically important game. Indiana plays at Ohio State in a matchup that effectively will decide who takes on Oregon for the Big Ten championship.

And for unbeaten Army, a showdown with Notre Dame is a chance to show whether it can compete on the national stage.

For some programs, this is truly a make-or-break weekend. Dreams of reaching a conference championship game or making the College Football Playoff may officially vanish with a loss.

We've assembled a brief preview of each Top 25 matchup—based on the latest AP poll, not the CFP selection committee's rankings—with a prediction for every game involving an FBS team.

AP Nos. 25-21

No. 25 Washington State (8-2) at Oregon State (4-6), 7 p.m. ET

Since a quality 4-1 start to the campaign, Oregon State has taken a nosedive. Last weekend's 28-0 loss to Air Force—which entered the game holding a 2-7 record—is a "rock bottom" type of result. Sure, Washington State just disappointingly lost at New Mexico, but there's not much reason to have confidence in Oregon State.

Prediction: Washington State 38, Oregon State 21

No. 24 Illinois (7-3) at Rutgers (6-4), Noon ET

In all likelihood, this will be a low-scoring game. Neither team commits many turnovers, but neither defense is particularly adept at creating them, either. I'll lean toward home-field advantage in such an even matchup.

Prediction: Rutgers 23, Illinois 20

No. 23 UNLV (8-2) at San Jose State (6-4), Friday, 10 p.m. ET

UNLV is markedly the better team, in my mind. Although strange things happen on the road, it seems like the expectation is more that SJSU should be able to hang around than UNLV will actually lose. It's tough to trust a San Jose State offense with four turnovers in three of the last four games.

Prediction: UNLV 37, San Jose State 24

No. 22 Iowa State (8-2) at Utah (4-6), 7:30 p.m. ET

Speaking of struggling offenses, Utah has mustered 259 and 272 yards—its lowest outputs of the season—over the last two weeks. Any hopes of an upset are heavily dependent on Utah's defense, once again.

Prediction: Iowa State 24, Utah 16

No. 14 BYU (9-1) at No. 21 Arizona State (8-2), 3:30 p.m. ET

For prediction, see No. 14 BYU.

AP Nos. 20-16

No. 20 Tulane (9-2), Idle

Wofford (5-6) at No. 19 South Carolina (7-3), 4 p.m. ET

After an emotional last-minute win over Missouri and before a trip to rival Clemson, the goal for South Carolina may be avoiding a sluggish start and building a comfortable early lead. But, as you can imagine, I'm not worried about the scorching Gamecocks against an FCS team.

Prediction: South Carolina 45, Wofford 10

No. 6 Notre Dame (9-1) vs. No. 18 Army (9-0) (in Bronx, NY), 7 p.m. ET

For prediction, see No. 6 Notre Dame.

The Citadel (5-6) at No. 17 Clemson (8-2), 3:30 p.m. ET

Clemson should quickly dispatch the lower-division opponents. The bigger story is Clemson has wrapped up ACC action with a 7-1 record in conference play. Without a loss from Miami or multiple by SMU, however, the Tigers will not be going to the ACC title game.

Prediction: Clemson 56, The Citadel 7

No. 16 Colorado (8-2) at Kansas (4-6), 3:30 p.m. ET

You want absolute chaos in the Big 12? Pull for Kansas, which upended then-undefeated BYU last weekend. Colorado's improvement looks genuine, though, and the Buffs are surging toward the league championship game. Kansas has a habit of playing close games, but CU keeps winning.

Prediction: Colorado 31, Kansas 26

AP Nos. 15-11

No. 15 Texas A&M (8-2) at Auburn (4-6), 7:30 p.m. ET

I hate my prediction. It's not a product of Texas A&M coach Mike Elko mistakenly saying "Our focus is singlehandedly on Texas. I mean, Auburn." in a press conference. Auburn is not good. Yet for one evening, as a desperate team at home in a night game, it might be good enough.

Prediction: Auburn 24, Texas A&M 19

No. 14 BYU (9-1) at No. 21 Arizona State (8-2), 3:30 p.m. ET

Arizona State understandably is favored, especially being at home. Despite the loss to Kansas, I'm not bailing on BYU because of its sturdy defense. But there's no question the offense is becoming a concern after scoring one touchdown in seven red-zone trips and converting just 4-of-22 third-downs attempts in the last two games.

Prediction: BYU 27, Arizona State 23

No. 13 SMU (9-1) at Virginia (5-5), Noon ET

On paper, I cannot find a convincing reason to expect Virginia will be a threat. The offense is a below-average unit and hasn't cracked 350 yards in a month, and the defense is 90th nationally in yards allowed per play. Nevertheless, the spread has hovered around 10 points. I envision SMU rolling, but what am I missing that Vegas sees?

Prediction: SMU 38, Virginia 21

No. 12 Boise State (9-1) at Wyoming (2-8), 7 p.m. ET

Just three defenses have surrendered more yards per carry than Wyoming. Ashton Jeanty is the best running back in the country. This is not a good combination for the hosts.

Prediction: Boise State 45, Wyoming 17

Wake Forest (4-6) at No. 11 Miami (9-1), Noon ET

Except for a disastrous Florida State team, every ACC opponent has scored at least 28 points against Miami. I fully expect Wake Forest's unique slow-mesh offense will be a problem for a defense that has dealt with a litany of issues from alignment to communication to execution. Simultaneously, the 'Canes should be able to score a ton of points on a bad defense.

Prediction: Miami 41, Wake Forest 31

AP Nos. 10-6

UTEP (2-8) at No. 10 Tennessee (8-2), 1 p.m. ET

Taking down UTEP? No problem. Finding a way back to the correct side of the projected College Football Playoff bracket? That, on the other hand, is a true dilemma for the Vols.

Prediction: Tennessee 48, UTEP 7

No. 9 Ole Miss (8-2) at Florida (5-5), Noon ET

Florida was a nuisance for Tennessee and Georgia before upsetting LSU, so the Gators certainly aren't being overlooked here. Given that Ole Miss is better on both sides of the ball, I'm not picking UF—but Ole Miss likely won't be comfortable until the fourth quarter, if at all.

Prediction: Ole Miss 24, Florida 13

Massachusetts (2-8) at No. 8 Georgia (8-2), 12:45 p.m. ET

As usual, SEC teams have a painless—well, it should be—nonconference game on the November slate. Georgia will cruise past UMass and set up a critical clash with rival Georgia Tech, where a victory should lock in UGA as a Playoff-bound team.

Prediction: Georgia 56, UMass 3

No. 7 Alabama (8-2) at Oklahoma (5-5), 7:30 p.m. ET

Oklahoma simply makes too many mistakes to believe it can assemble a shocking win over Alabama. The offense has lost multiple turnovers in four straight SEC games, and Alabama has notched three-plus takeaways in five straight tilts.

Prediction: Alabama 38, Oklahoma 17

No. 6 Notre Dame (9-1) vs. No. 18 Army (9-0) (in Bronx, NY), 7 p.m. ET

The short version is Notre Dame's defense should rule the evening. But how about Army's physical group? While the competition level is lower for Army, only one opponent has surpassed 14 points. This is an informative matchup about ND's offense and Army's upside.

Prediction: Notre Dame 28, Army 19

AP Nos. 5-1

No. 4 Penn State (9-1) at Minnesota (6-4), 3:30 p.m. ET

Minnesota must be respected, considering the defense has yielded just 17.7 points per game. The problem is Minnesota's offense has notched a conference-low seven gains of 30-plus yards, and lacking explosiveness against a sturdy Penn State team is asking for trouble.

Prediction: Penn State 27, Minnesota 13

Kentucky (4-6) at No. 3 Texas (9-1), 3:30 p.m. ET

Look, I have no confidence in anything about Kentucky. I think the Wildcats play up to their competition—see Georgia, Ole Miss and even Tennessee—but they've also had several awful performances this season. Texas wins, largely since UK averages 14.1 points against power-conference teams. Will it be close or a blowout? Who knows!

Prediction: Texas 34, Kentucky 14

No. 5 Indiana (10-0) at No. 2 Ohio State (9-1), Noon ET

This is a tremendous prove-it opportunity for Indiana, which has received criticism for a soft Big Ten slate. Right or wrong—and, remember, the conference put that together—the noise can be silenced with a strong day at Ohio State. Though the Buckeyes should win because of their defense, a turnover or two could flip the game in a hurry.

Prediction: Ohio State 27, Indiana 16

No. 1 Oregon (11-0), Idle
