The Hawks could use the work, because I think they'll be more of where that came from in the coming weeks. If they see a ton of blitzes this week, and handle it, it may cause others to re-think, at least a little, that as a defensive strategy.
Don't get me wrong. You should hope Ball State blitzes so Iowa can work on their assignments when the blitz comes. It will be good practice. But there is no way it deters other teams from blitzing Iowa. This is Ball State we are talking about.
