He may have been completely committed in his mind to come to SU when he signed it.
He may have been told, “Sign it and there will be a 1 year scholarship guarantee if you decide you want to go to college”. It is, after all, not a binding agreement. You don’t have to go and the school has no legal recourse if you do not.
There’s risk in this for the recruits and the schools. These are the colleges rules, through their association, the NCAA.
