ISU has seniority and the urgency to win, if this is the best team in ISU history they cant have their seniors go 0-4 vs Iowa.
Iowa has the momentum, just play within the game plan and i don't think ISU break the record of 22 some games without giving up 24+ points.
here is my deciding factor...give me an example of Purdy beating a good defense, the two chances i know of are vs us (not the best game, he had 1 TD pass on broken coverage) and then when they played Notre Dame two years ago in a bowl game and got blown out. Yeah he puts up video game Heisman #s vs Big12 defenses, but vs good defenses with pressure in his face not so much. Does he buck the trend this year? break the Iowa D record of games without giving up 24+ points?
here is how i see it:
Iowa turns ball over, giving easy possessions to ISU and ISU wins a close game, Or Iowa wins by a couple of possessions, D continues to play well, bottles up Hall and forces Purdy into mistakes.
Not trying to be a homer but main factor for Iowa win is to play field position and not give up big plays (Genius i know!)
For the other posters...what is the best Defense Purdy has beaten?
