No. 9: Cole Aldrich, 860 rebounds, 2007-2010
Aldrich played just three seasons at Kansas before going to the NBA, but he was a force. He was a member on the 2008 National Championship team and he played in 111 games, 97 of which the Jayhawks won.
He scored 1,038 points in those season, with 72 assists and 59 steals. He also blocked 253 shots. He had the first official triple-double in KU history, when he scored 13 points, pulled in 20 rebounds, and blocked 10 shots in a 2009 NCAA Tournament game.
For his career he pulled down 860 rebounds, good for an average per game of 7.7, and includes him averaging 11.1 during his sophomore campaign. If he had returned for his senior season, he most certainly would have been in the top five, but still his accomplishments in three seasons are fantastic.
