We've already seen a reinvention of Kirk ... and that produced the 2015 season. Obviously, a favorable schedule helped .... but anything can happen on any given Saturday. Iowa throttled OSU this year, Syracuse beat Clemson, and Pitt beat Miami.
Kirk's reinvention was reminiscent of Penn State's reinvention back in 2005 ... and that was with Paterno at the helm. Given Kirk's respect of Paterno's program (at least before all the Sandusky stuff came to the forefront) ... it's not surprising that Kirk managed to pull a comparable turnaround.
Similarly, if you consider Iowa's personnel and schedule through the coming seasons ... there's no reason to suppose that Iowa couldn't pull off a more great seasons.
