A lot can happen but him missing his junior football season definitely would slow down his football prospects. That being said, he is a freak athlete and a few good camps (in shorts and t shirts) and he can rack up some big time offers in a summer.
The way the rules are setup, he has a full scholarship offer by default on any football team so I imagine all the football coaches (Franklin, Campbell, Ferentz, Gundy) were informed and signed off on it. That used to be nice in that he doesn't count against wrestling scholarships but with roster cap rules, it doesn't let coaches add another kid.
He absolutely is a legit football prospect though, have to remember, none of us are Georgia/Oregon/Texas/Ohio State etc and we regularly take freak athletes who have a high ceiling but need polishing.
