This Saturday, the Kentucky Wildcats and Louisville Cardinals will square off in men's college basketball. It's one of the game's most intense rivalries. The Cardinals are the defending national champions. Kentucky won the title the previous year after defeating Louisville in the Final Four. The teams' modern rivalry dates back 30 years, when Louisville was coached by Denny Crum and Joe B. Hall was at the helm at Kentucky. The two Hall of Fame coaches, once fierce competitors, are now on the same team, hosting a popular radio show.
