Mike:
You will recall that the Iowa/Michigan State game was a tenacious, hard-hitting game for both teams. Some of the hits were almost vicious. Iowa had four players sustain injuries in that game. I would like to make the point that Michigan State in subsequent games was not the same team that played against Iowa. I think Michigan State also sustained a huge toll from that game and a let down thereafter. Before they played PSU, Minnesota scored 42 points against them and Purdue scored 37 points against them. Therefore, it should be no surprise that PSU scored 42 points against them. Thus, as others pointed out, I think you should have ranked Iowa ahead of PSU.
