Well there is a reason he is on football scholarship. Even if someone plays two or three sports, if football is one of them it must be the scholarship sport.

Cassioppi gets hurt and Iowa decides to use him and go for a medical for Cassioppi and let him redshirt the following season. I don't think he does much this year if he wrestles though, much like Carroll (SO REDSHIRT BOTH OF THEM).
