If I was a defensive coordinator against ISU, I would coach my defenders to take the running back out of the read option and make the QB run the ball. ISU has several running backs with experience and only one QB with experience. The quickest way to shut down ISU's defense, is to put its starting QB on the sidelines. The backup QB is a redshirt freshman who has never played. If he goes in, the offense will probably be very simple. I would bet that this is what UNI did in the first game. Sam Richardson ran more than 20 times in that game. Every time he runs, the defense gets their shots on him. The more he gets tackled the greater the chance he will end up on the sideline watching the game. If the defense takes the running back out of the read option, our coaching staff has to protect their QB and stop running the zone read. The end result of the UNI game was Sam Richardson was injured. It impacted his game against Iowa. When he did run he went down quick before he was hit, gaining little. According to our coaches today, his ankle made it hard for him to set his feet properly when he was passing and he was off target most of the first half.
