Hold on there. Are you saying:
(1) that Ferentz's coaching style is unacceptable to you (Ferentz has kept KOK on all these years so a valid assumption would be that Ferentz likes KOK's performance, and you insinuate that Ferentz is incapable of firing KOK)?
(2) that the scoring defense and LACK of effectiveness in the 4th quarter of this year's team helped to translate to more wins and less losses?
(3) that Iowa's defense is well equipped to stop one-on-one offenses like passing offenses, and spread offenses?
(3B) that it's OK that Iowa loses or struggles against any Big Ten opponent that uses a spread, passing, or one-on-one offense - it's easier to point out Iowa's Big Ten opponents that don't use those offenses: Penn State, Minnesota, Nebraska, and Michigan State - has Iowa's defense become outmoded?
Finally, this crap about Iowa's bend but don't break defense: in crucial situations, it seems long passes are being completed all the time. When defensive gaps are broken down, the defense gives up long runs because there is inadequate speed on defense.
