First, I find it interesting that JR and his dad think JR would find any other schools interested in his QB skills. Frankly, having started for the last 2 years, if anything he regressed in 2014 (KF bears some responsibility). If he was to put together a highlight video of his best plays this past season, what could he show that would prove that he's Division I material? The last quarter of the Ball State game and the Northwestern game, anything else?
I'm sorry but JR does not have much to market to anyone else, but if he and his dad think he does, then I hope they press the issue with KF and Kirk cuts him loose. Iowa is never going to build an offensive program that appeals to potential recruits with a QB with JR's skills. As Jon Miller has stated many times, Iowa's WRs run wind sprints in games, there is no serious deep threat because JR does not have the arm strength to make the play.
If I was either QB, I would press the issue with KF because they both deserve to know where they stand and how future playing time will be decided. If he cannot or will not give them a straight answer, then they are both better off looking for a program that will utilize their skills. In such an event, I'm positive that CJB would have many more schools interested in him than JR, regardless of the type of offense being run.
