I thought Jack is in his Sophomore year in HS. So Fran has 2 more years at Iowa...he is not going to walk away from guaranteed money and the jobs that are available to him are mid major that would be big paycut.
If Iowa were to retain Perkins for another year, Iowa has prety good returning cast for next year. No matter how good they are on offense, they are always going to be DOA in NCAA tourney because teams expose players like a Krikke or Pmac or Payton Sandfort. Iowa is short on guard talent. Harding and Bowen don't appear to have shooting ability.
