The Kentucky-Louisville basketball rivalry is the best rivalry in college athletics. I've read that a few times this week. I don't believe it.
It's a great rivalry. I've spent a little time in Louisville and a lot of time in and around Lexington. Kentucky's support can overwhelm you. While Louisville lacks the numbers Kentucky has, it does have a nice urban edge and attracts all the fans that can't stand the Wildcats.
The North Carolina-Duke basketball rivalry obviously is intense, enhanced by proximity Kentucky and Louisville can't match. Kentucky-Louisville supporters will claim their rivalry is greater because they don't have professional sports in their state to interfere.
This season, North Carolina doesn't, either.
I've experienced other great college rivalries -- notably Texas and Oklahoma football and, closer to home, South Carolina and Clemson football.
But the most intense rivalry I've witnessed is Alabama-Auburn football. I've never seen a rivalry as partisan or fans as passionate.
