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 top-ranked Tennessee Volunteers tussle with the No. 8 Florida Gators in SEC college basketball today. This game is available to watch on multiple streaming services for free.

Tennessee (14-1, 1-1 Southeastern Conference) missed its first nine shots, trailed by double digits a few minutes later and never recovered. The Volunteers got bullied in the paint, outmuscled on the boards and beaten up and down the court.
