College Football Power Rankings: How did the Top 25 look in Week 12? - ESPN

Texas A&M's Saturday began with reports about a contract extension for coach Mike Elko, continued with the team falling behind 30-3 to South Carolina on its home field and ended with the team capping the biggest comeback in its history.

Although the Aggies left Kyle Field at 10-0 for the first time since 1992, they have areas to improve as the most important games, including their first College Football Playoff appearance, are ahead. Texas A&M's defense was inconsistent Saturday and has been for much of the season. Quarterback Marcel Reed showed a bit of everything. Elko certainly will seek steadier play going forward.

Texas A&M isn't the only top-25 team that needed to brush up on a few things after Week 12. Michigan went to Chicago's Wrigley Field and committed five turnovers but still outlasted Northwestern 24-22. Speaking of turnovers, Alabama had three in its home loss to Oklahoma, half of its season total coming into the game. The Tide also continue to seek a jolt to their running game.

Ole Miss wriggled free of Florida and won 34-24 in a game in which both fan bases want coach Lane Kiffin, but the Rebels undoubtedly will be working on their red zone offense ahead of the Egg Bowl. Georgia Tech is still alive in the ACC race but has given up a combined 82 points the past two weeks.
