55. Emeka Okafor, Connecticut

Emeka Okafor was one of, if not the most, dynamic centers in college basketball in the past decade. In 2004, he led Connecticut to its second national championship under coach Jim Calhoun. Okafor was awarded the Most Outstanding Player award in the Final Four, averaging 21 points and 11 rebounds in the final two games. His true impact on the game was felt on the defensive end. His ability to block or alter opponents' shots was a game-changing component of the Huskies' defense. He led the country in blocked shots with 4.3 a game during the 2003-04 season, and his intelligence on the court made him one of the most intimidating defenders in the country. -- Bruce Pearl
