Red shirting makes no sense in the 13 scholarship limit era. Doesn't seem to be much value in investing 5 years for a player not ready to play. If they do develop positively, they often go pro or transfer.
I don't know about how offers are prioritized. We also offered Jayson Tatum, Harry Giles and others early. They obviously did not reciprocate interest. Didn't know if Guy was in that category.
