Presently, in Big-12 conference-only games, ISU is the only school that has only one person in the rebounding Top 25, and it is Brockington, a guard. Not surprisingly, ISU is last in conference-only games for team defensive rebounds, and 9th in conference-only games for team offensive rebounds. Given the way ISU shoots the ball, there is plenty of opportunity for offensive rebounds, but ISU doesn't get many (I guess not surprising given the offensive scheme).
Lampkin is currently #6 at 6.8 RPG, and Cisse is #14 at 5.9 RPG. Either one of them would be a welcome addition to ISU's roster.
