Thirteen weeks of college football have now passed, with just one more regular season game remaining. As the College Football Playoff looms, former coach-turned-ESPN analyst Dan Mullen has updated his top 25 rankings. This article will take a detailed look at the teams and players that have made an impact during this crucial time.

Key Takeaways and Updates

Indiana's Fall from Grace

After a 38-15 loss to Ohio State, Indiana took a significant hit, dropping from No. 2 to No. 11. This loss was a major setback for the Hoosiers and shows the tough competition they face in the Big Ten.

Ole Miss and Alabama's Struggles

Both Ole Miss and Alabama fell out of the top 10 after suffering their third losses of the season. These teams, which were once considered contenders, now find themselves in a more challenging position as they approach the postseason.

The Buckeyes' Ascent

Following their win against Indiana, the Buckeyes moved up from No. 4 to No. 2. They now stand as one of the top teams in the Big Ten and are a strong candidate to face Oregon in the conference title game.

The Only Undefeated Team: Oregon

With Indiana and Army losing, Oregon remains the only undefeated team in college football. They have already clinched their spot in the Big Ten Championship game and will look to continue their winning streak.

Heisman Trophy Candidate Dillon Gabriel

Dillon Gabriel has been a key factor in Oregon's success this season, with 3,066 yards passing and 22 touchdowns. His performance has been crucial in keeping the Ducks in the hunt for the College Football Playoff.

Ohio State's Path to the Championship

After defeating Indiana, Ohio State can clinch their spot in the conference championship with a win against rival Michigan. This would be a sweet revenge for the Buckeyes, who have lost three straight games to the Wolverines.

Texas' CFP Hopes

Texas' only loss this season came at the hands of Georgia, but they have won four straight games since then. If they can make it to the conference championship, their CFP hopes seem secure.

Notre Dame's Climb

Notre Dame moved up one spot in Dan Mullen's top 25 after defeating Army. Running back Jeremiyah Love played a key role, scoring three touchdowns and rushing for 130 yards.

Penn State's Season

Penn State's only loss was to Ohio State, but they are on pace to make their first College Football Playoff appearance. Their strong defense and efficient running game make them a dangerous team.

SMU's Championship Bid

The Mustangs clinched their spot in the ACC Championship game with a 33-7 victory over Virginia. Quarterback Kevin Jennings and running back Brashard Smith have been key contributors to their high-scoring offense.

Miami's Offensive Prowess

The Hurricanes lead the country with 44.7 points per game and can still clinch their spot in the ACC title game with a win against Syracuse. QB Cam Ward has been a standout, with 34 passing touchdowns.

Georgia's Conference Title

Georgia officially clinched its spot in the SEC title game with tiebreakers. They currently rank No. 10 in the College Football Playoff rankings and will face the winner of the Texas A&M vs. Texas rivalry game.

The Vols' Climb in the Rankings

After losses by other SEC teams, the Vols moved up from No. 13 to No. 9. Running back Dylan Sampson has been a dominant force, with 1,307 yards rushing and 22 touchdowns.

Boise State's Heisman Hopes

Ashton Jeanty is one of the leading candidates for the Heisman Trophy, having surpassed 2,000 yards rushing. Boise State is a dangerous team and could make a strong showing in the College Football Playoff.
