No. 2: Raef LaFrentz, 1,186 rebounds, 1994-1998
Like Collison and the player at number one on this list, LaFrentz is in the top three all-time in both scoring and rebounds. He was also a two-time consensus first-team All-American.
He played in 131 with the Kansas basketball team, starting all of them. The Jayhawks won 123 games in his years at KU.
He scored 2,066 points, averaging 15.8 a game. He recorded 1,186 rebounds at a 9.1 per game clip. While he may not have been as great of an all-around player as a few other guys on this list, he was an outstanding one, and one of the best in school history!
In a crazy statistical happenstance, his rebounding total fell just one short of tying the school record, and two shy of setting a new mark.
