Absolutely agree.
While Iowa's offense was obviously horrible this year, it is never going to be a top 50 offense, just like we will likely never have a defense outside the top 20.
KF wants to limit possessions, move the chains, keep the ball in front of his defense and as far away from his goal line as possible, no turnovers and limit penalties...play clean football. This style isn't going to put up huge numbers on offense, nor will it give up huge numbers on defense.
I like watching these big offenses but damn do they play some terrible defense. As an Iowa fan perhaps I've been conditioned, but I'll take the great D, bad offense, over the great offense, bad defense.
