But, do you understand WHY the part I bolded happens? Do you think it is simply because Iowa is teaching their guys not to attack? Because the truth is, counter offense is exponentially better than it was in the Gable era. Simply attacking more is NOT all of a sudden going to make Iowa win more championships.
Hell, even PSU has been much more defensive across the board over their last 2 championships. The simple truth is positioning is so much better now than ever before. Kids are coming into college with the neutral fundamentals so ingrained that breaking through the head-hands defense is ridiculously hard. Couple that with constantly trained re-attacks and, unless you are pure grease lighting, you just aren't attacking without near perfect set-ups. Mind you, these type of set-ups are few and far between BECAUSE of that head-hands defense.
With all that said, Iowa guys ARE actually successfully attacking quite often against any of their opponents not in the top 8-10 range. Why? Because nearly all their guys are significantly better than their opponents outside that range. Simple common sense comes into play once your opponent is as good as you or better...
