Iowa needs to keep the culture , Defense and STs whenever Kirk steps away, Iowa will never get the skill position players the Coasts and South gets so You make a hire that assures You keep what is working but is willing to fix the Offense . Iowa will be walking a tightrope the next hire which is why I suspect they will either hire from the current Staff or the new incoming Coach will keep some of the current staff on, Iowa has a playoff level defense and STs , only a complete mental midget would risk losing those 2 phases .
