AP College Football Poll 2014: Official Top 25 Rankings and Week 15 Projections

Whether teams are putting the finishing touches on a College Football Playoff resume or simply building momentum for a better bowl invite, there are rarely higher stakes than in Week 15 of the season.

It's conference championship weekend, which means Alabama, Oregon and Florida State will all be put to the test one last time against a dangerous conference foe. Elsewhere, a pair of Big 12 teams in TCU and Baylor will wrap up their nine-game conference slates in the hopes of sneaking into the CFP. 

Needless to say, we may be one week away from the Top 4 being decided, but there is still plenty of work to do for teams in the running. With the stakes higher than ever, let's break down the Week 15 tilts between Top 25 foes.

Upset Pick: No. 6 Ohio State over No. 11 Wisconsin

It might not be an upset in terms of seeding, but as far as the odds go, the Ohio State Buckeyes will be pulling off the upset when they slip past Wisconsin to win the Big Ten title.

Of course, a primary reason for the Badgers' favorite status has nothing to do with anyone playing, but someone who won't play. Ohio State's quarterback J.T. Barrett fractured his ankle Saturday against Michigan, per ESPN.com's Austin Ward, and is out the rest of the year.

The Buckeyes have now lost two star quarterbacks in one season, which means they'll now strut out an inexperienced Cardale Jones against Wisconsin, per SportsCenter:

Barrett's fingerprints are all over this offense, having been the one who single-handedly led them back to prominence after early-season struggles. But now that this offense is rolling, who is calling the shots won't matter as much as you think.

Case in point—on his first drive, Jones led the Buckeyes into the end zone against Michigan late to make it a two-score game. Ohio State offensive coordinator Tom Herman agrees, per Cleveland.com's Ari Wasserman:

"

The quarterback doesn't have to win games for us, the quarterback has to manage games and distribute the football and lead. We've seen that throughout this season. As long as he's mentally prepared and he's got a ton of physical tools ... I have nothing but the utmost confidence in him because of what we've got around him.

The Badgers' dominant rushing game is another reason why they are favorites, with Melvin Gordon breaking records left and right. But Ohio State's strength on defense is up front, and some early stops will put the pressure on Joel Stave to make plays against defensive backs who will be ready to pounce.

Wisconsin's downhill running will keep it close, but the Buckeyes just have too many weapons on offense for Jones to utilize. 

Prediction: Ohio State 28, Wisconsin 24

Lock of the Week: No. 22 Boise State over Fresno State

No. 22 Boise State has a chance to lock up another Mountain West title Saturday, but even larger aspirations will spur the Broncos to a resounding beating of Fresno State.

Since now-unranked Marshall's perfect season has come to an end, Boise State is well in control of that coveted spot for any team outside the Power Five. As the only one ranked and no other true contenders, the Broncos could wrap up a spot in the Fiesta Bowl—or another marquee bowl—with the win.

Needing style points down the stretch, the Broncos have laid it to their last two opponents, outscoring Wyoming 63-14 and Utah State 50-19. Boise State running back Jay Ajayi has been simply unstoppable, with eight touchdowns in his last two games.

A five-touchdown performance against Utah State put Ajayi near the NCAA lead in a number of categories, per KTVB's Jay Tust:

While the Broncos have looked unstoppable ever since their early-season loss to Air Force, the Bulldogs have hardly looked dangerous of late. With only two teams above .500 in conference play in its division, Fresno State practically made the title game by default.

Boise State only held off the Bulldogs 37-27 when these two squads faced off in Boise in October, but the Broncos offense has transformed since then around Ajayi. Meanwhile, the Bulldogs have won three straight—all against unimpressive opponents, however.

Expect the Broncos to blow open the spread as they look to woo voters.

Prediction: Boise State 49, Fresno State 20
