Brown: UK has nation's top two teams

— -- SMU coach Larry Brown is convinced that the Kentucky Wildcats can go undefeated this season -- with either one of John Calipari's two top-ranked teams.

"If you take their first and second teams and split them up, they'd probably have the No. 1 and No. 2 teams in the nation," Brown told USA Today. "John should go 45-0 with that talent."

With a No. 1 ranking in the Associated Press and USA Today polls and a squad that features a record nine McDonald's All-Americans, Kentucky has been the focus on the college basketball world throughout the preseason.

The Wildcats play 31 regular-season games and -- even with the SEC and NCAA tourneys -- won't play 45 games. But could they go undefeated?

Bob Knight's 1975-76 Indiana squad is the last team to finish a season with an unblemished record.

Kentucky has been pegged as the program that might duplicate that feat in recent years under Calipari. His 2011-12 squad, which included  Anthony Davis, lost just two games that season.
