A week that saw the three final undefeated teams lose -- two by a lot (OU to Alabama and Tennessee to Florida) and one by a little (Florida to Kentucky) -- prompts major changes in this week's college basketball power rankings.

The Vols have shown the ability to shut down high-level offenses, limiting Baylor to 62 points and holding Illinois to 64 points on 29% shooting. Tennessee has the lockdown perimeter defense to contain Florida's explosive backcourt, but the Gators don't have the defensive chops to limit the Vols inside.
