There's a lot of football left to be played this season, but one of the biggest regular-season games is already in the rearview mirror. Alabama defeated Texas A&M on Saturday in a 49-42 shootout at Kyle Field, and the Crimson Tide are expected to remain in the driver's seat in the SEC West and in the national championship race the rest of the season.

Our drive-based, opponent-adjusted FEI ratings are still somewhat influenced by preseason projected data due to the limited amount of 2013 game data that's already in the books. The early weeks of the season have had a big impact on teams' rankings (Texas fell from No. 6 to No. 56 in the last two weeks) and a few have moved up significantly -- Central Florida, Washington and Arizona all started the season outside the top 40 and have since moved into the top 20 in FEI after strong starts.

Which teams can continue their strong starts and potentially win out over the remainder of the regular season? Here is a rundown of the 10 teams most likely to remain undefeated.
