The biggest difference in talent was obviously on the DL. We saw the #1 defensive line in all of college football against the # 110 line (and that might be generous). If you switched those two lines, ISU could have won this game.
Look......IOWA looked great today but lets not get crazy. I'm certainly not ready to put them in the National Title Game quite yet.
There are a LOT of very good teams out there. ISU is NOT one of them.
