Line play and QB, and WR play were all bad in the Iowa game. The system does not throw the ball 15 feet over receivers head, or drop pass, or let the other teams players come through untouched. Iowa is not a team that you can make any mistakes against, and then you need to get some lucky bounces. None of that happened last week. The system is not the problem, the players are just not good enough to execute the offense against a very good defense. If ISU ran the pro set the same problems would show up.
