Bluegrass showdown: Kentucky, Louisville ready to tangle again with the stakes mighty high

John Calipari sent Andrew and Aaron Harrison and three other freshmen to sit behind the microphones and talk about Kentucky's upcoming Sweet 16 matchup against Bluegrass State rival Louisville.

Rick Pitino sent up seniors Russ Smith and Luke Hancock.

That, as much as the 70 miles that separates the schools, is the gulf between the neighbors who play Friday in one of the most important meetings in their long, colorful and not-always-friendly rivalry.

Eighth-seeded Kentucky plays the one-and-done game. Fourth-seeded Louisville goes for a more long-term approach.

They meet for the second time in the last three years in the NCAA tournament. Kentucky won the 2012 Final Four matchup on the way to the national title.

This year's winner plays Tennessee or Michigan in the Midwest regional final Sunday.
