The SEC hasn't won a National Championship since 2012, which is an eternity for the most powerful conference in college football. Who will step up this year and regain the crown? It could be the Alabama Crimson Tide, who are +650 second favorites on the NCAAF futures market at press time, or the Auburn Tigers, who are fourth to win the title at +900. As usual, it should all boil down to the Iron Bowl in late November. This is arguably the most competitive rivalry in sports, and the odds say either team could end up winning the SEC – Alabama is a slight favorite at +210 over Auburn at +275. It's a big step down from there to the top contenders from the SEC East: the Georgia Bulldogs are +500 to win the conference and +3300 outsiders to win the National Championship. Alabama's 2015 season starts with a bang on Saturday, September 5, as the Crimson Tide face the Wisconsin Badgers at Cowboys Stadium in Arlington (8:00 PM ET, ABC). The Tigers have a relatively comfortable season opener at the Georgia Dome against the Louisville Cardinals (3:30 PM ET, CBS).
