March Madness: Apollo 11 Moonwalker Buzz Aldrin Pulling Hard for Villanova

Buzz Aldrin is hoping to do some serious gloating this weekend. The Apollo 11 moonwalker is taking on ESPN college basketball analyst Dick Vitale in the fourth annual "Allstate March Mayhem Challenge," a competition to see who can pick the most accurate bracket for the NCAA men's basketball tournament. The tournament field has been whittled down to its Final Four, who will take the court on Saturday (April 2): Villanova will play Oklahoma, and North Carolina will battle Syracuse.
