Yeah, I see he only has two P5 offers which is a lot less than Downing
Virginia also has offered Ince recently.
Did you look at 247 recent ratings? ISU at 33 Iowa at 48. ISU also has 3 more commits so that means when Iowa gets up to 8 things should be about even at this point. I am going to guess Iowa ends up in the high 40s low 50s with ISU in the high 50s.
No link for the gut feeling on getting more offers. I was going by recruiting logic.
Also, with ISU being virtually unknown to the out of state guys (same as Iowa) I would be worried about the guys from Florida, Mississippi, California and even Texas because as an Iowa fan knows, when you get pressure to stay closer to home, you can get swayed easily by a school that is better.
