I have no idea if CJ did or did not have offers from Xavier or Indiana - but I really question a kid for wanting to "walk on" at Iowa instead of accepting a scholarship at a perennial college basketball power like Xavier or Indiana. Remember, he accepted the walk-on position BEFORE being offered a hok scholarship (due to CW leaving). This is especially baffling when I consider that he doesn't appear to have family connections to the Hoks.
If my oldest daughter was good enough to play D1 basketball and had 3 offers : accept a scholarship at OU, accept a scholarship at TxA&M or go to ISU as a walk-on (with no absolute guarantee that a player like Maddie Wise was going to transfer out & open up a scholly for her), I would strongly encourage her to take one of the first 2 options. For as much as she loves the Cyclones, she would jump at the chance to basically have little to no debt after getting her college degree (and to be on a very, very good P6 team).
