The SEC's national championship streak may be alive and well, but that doesn't mean there's no room for debate over which is the best league in college football.
With six of the top 12 teams in the preseason Associated Press poll, the SEC had a clear edge in public opinion just three weeks ago, and it still leads the way with seven teams ranked in the top 25. But a contender to the throne is emerging. The Pac-12 has five teams ranked in the AP poll, six teams in the top 25 of the Sagarin Ratings and the best nonconference résumé of any league so far in the 2013 season.
Unlike the SEC, however, the Pac-12 may be too deep for its own good.
Brad Edwards writes that while the Pac-12 has a solid argument for being the No. 1 conference in college football this season, and could stay that way in the BCS computers, the league's impressive depth could end up hurting its BCS title chances.
