The thing Iowa has, and TO had, and really any program that can achieve longevity in a HC. The program as a whole becomes very good and being consistent. A system gets put into place and it becomes an automatic machine. From how they recruit, to who they recruit, to schemes, to weight room, to player development. This all starts from the moment a player steps on campus freshman year. Everyone is on the same page. This automatic system is what Frost wants to accomplish as well.
In Iowas case, they have become very very good at Ferenz system. Usually that means they are able to fill spots pretty easily without falling off too much. Unfortunately for Iowa, Ferenz system is also very good at only being able to get 7,8, and 9 wins. Not a knock just reality of the situation. Having a system in place is great in some way, but bad if that system can't get over the hump of mediocrity.
So long story short, Iowa may take a slight step back this year. Probably nothing too drastic. Either way Im guessing the results will end up very similar as the last 20 years.
