or you can get 1$+ million guaranteed this year like THT will and if he washes out in the NBA (not likely, as he'll get multiple chances) he can play professionally overseas for 10+ years then go back to college and finish out his degree.
I don't know if Talen would have stayed at ISU knowing he'd be picked 46th but he still will be be paid and be able to help his family. Lindell and Cam are examples that probably should have stayed but both felt like they were done with college and prepared to take the long road to the NBA, They all made the choice best for them.
