After watching replay, Lafayette had legitimate sized bigs who played down low and there were a handful for Tosan. Hooks and Barnes were simply overmatched. Hooks is actually regressing which is not unusual for a freshmen both on the defensive and offensive end.
Although IL is not loaded with bigs, i.e. Atkinson in his Yale days, they do need to get Kellman back on the floor as Tosan can get in foul trouble due to his aggressive defensive play. They need Kellman for 10-15 minutes for sure unless Hooks somehow progresses.
