The #1 problem holding the Iowa football program back during the KF era is consistently losing close games, most of them occurring against generally inferior opponents. All of the disappointing/mediocre seasons are littered with single score losses where the outcome of the game hinged on just a play or two. Go back and look at the scores from 2001, 2005, 2006, 2007, 2010, etc. Flip just a few of these games each year and KF has a lengthy string of 8+ win seasons similar to what Hayden did. Hell, even KF's unquestionably good teams had several excruciating losses that never should have happened.
