We came out as conservative as I've seen in quite some time, probably mainly to protect Thompson. I think its clear we were hoping to just keep the game close until the 4th quarter. Granted, I think we thought we could get more push from the offensive line, but our 2 back delayed power got destroyed by ISU. We tried a few passes and the typical play action with 2 back, but we usually only had 2 WRs on the field so its tough to get anyone open. In the 4th we finally opened it up.
Of course, none of that explains the absolutely moronic 4th down run call to Thompson, but for the most part that's that the game plan looked like IMO.
