It’s October, and as crazy as it sounds, there will be quite a few college football teams who have completed half of their season by the end of this weekend. Still, while these last five weeks have given us plenty of ups, downs and great games, one thing remains painfully similar to every other season over the last half decade: The road to the national championship appears to go through Alabama.That’s right, as much as things change in this sport, they stay the same in T-Town, where the Crimson Tide started the year No. 1 and haven’t budged, all while breaking in a true freshman at quarterback and replacing a Heisman Trophy-winning running back. But while the Crimson Tide look unbeatable through five games, there are a select few teams that can actually knock them off.Here are the only nine teams in college football who can beat the Crimson Tide, some they’ll actually face in the regular season, and some they might face in the playoff. To all the teams listed below, good luck. You’ll need it.
