This was Louisville's last appearance in the Final Four until 2005, where they would lose to Illinois in the semifinal.

This also remains the last official national championship won by the Cardinals, along with their last official appearance in the championship game. They would return to the title game in 2013, where they defeated Michigan to win what was their third title. However, Louisville was forced to vacate their title due to a massive sex scandal involving players on the team, and as a result the Cardinals had four seasons from 2012 to 2015 wiped from the record books. The Cardinals became the first team to vacate a basketball national championship, and the second team overall to vacate a national championship in college sports after USC vacated its 2004 national championship after an investigation into the eligibility of Reggie Bush.
