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.

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.

The Gators are coming off their first loss of the season as they play host to the Volunteers, ranked No. 1 in the Top 25 And 1

The men's college basketball AP Top 25 will get a shakeup at the top this week, as the Tennessee Volunteers suffered their first loss of the season, a blowout to the Florida Gators. Meanwhile, the Georgia Bulldogs crack the ranking for the first time.
