I think too many people are scared off because he
1. Played in a small conference
2. Scored a lot of pts
When you actually look deeper into the situation you see there's A LOT to like. Penn's breakdown on his passing numbers in PnR situations was money.
Great character, smart player, tested out very well athletically, lights-out shooter, great in PnR situations/pretty good ball-handler, gets to the FT line a lot
I'll be shocked if he doesn't work out at this point. There are just little to no signs that he won't.
