The mighty Southeastern Conference's aura of invincibility has taken a hit just a couple weeks into this season.
Sure, the SEC has half its members ranked in the Top 25 this week, and the conference keeps grabbing big headlines with its schools playing the country's must-see games every week. No. 1 Alabama and sixth-ranked Texas A&M are next up Saturday.
But the SEC's dominance in nonconference play has slipped.
The league of champions already has lost four nonconference games - half as many as the SEC had all of 2012. The SEC has lost to the Atlantic Coast Conference, the Big 12 and even the Sun Belt. This week, the American Athletic Conference and Pac-12 are lining up to take a shot at college football's power conference.
