Consistency within a coaching staff or executive staff is a great thing, but it usually gets to a point of weakness because everyone knows everyone and no one challenges anything and nobody fears for their job which creates an eventual atmosphere of severe complacency in areas that used to be strengths. Iowa is at this point. KF needs to infuse some new blood. Not a massive, one year overhaul, but 2 here, 2 there. And if he doesn't see thud, he is not doing his job and is letting old loyalties cloud his judgement. Special teams and defense come immediately to mind.
