Still the top team in the country until they show otherwise.  This weekend against Ole Miss will be a great test of their defense and potentially their offense.
Alabama remains Alabama until proven otherwise. They have 3 opponents in common with Georgia this year so it'll be interesting to see how the 2 teams play against those shared opponents as they head toward what seems like an inevitable play-in game in December and a possible rematch in the CFP.
The reigning champs are 4-0. Their best win is over Florida (3-1). They are probably the best team in the country and have a good chance to get back on top perhaps with a matchup vs. Ole Miss this coming weekend.
