Iowa doesn’t necessarily recruit kids just based on the position they are playing in high school. Chad Greenway was a high school QB. Iowa recruits kids they feel they mold into the players they need. It has been working fairly well for the past 20 years.
I know thinking probably isn’t your strong suit, but you can’t simultaneously argue Iowa doesn’t recruit based on positions while also relying on positional rankings as important. If Iowa isn’t using player as DE it’s irrelevant what they are ranked as a DE - especially considering you don’t believe they will all a DE. If you’re going to spend time trolling on a rival school’s forum, is it really too much to ask that you at least to it somewhat intelligently?
