I was at a local HS game over the weekend to watch Moline play who has two guys who are 3 star top 150 players set to go to Iowa next year.
Owen Freeman is 6'10" post and Brock Harding is 6' PG.
All I will say is Freeman compared to Perrin is not close. Perrin is pretty skilled and athletic and looks like he might potentially play some limited backup minutes later in year if he can adapt enough to the speed and physical play.
Freeman is a project. Slow, soft, and limited ball skills.
Harding is interesting player. Not exactly sure how his game will translate in slugfest BT. Certainly a high mid major kid.
Old school pure PG, great vision, great passer, plus handles, nice shot with range, fairly quick, very crafty, and apparently can actually dunk.
Small frame and likely will have issues on D, but Iowa does not guard.
