Iowa State coach Dan McCarney won’t change the rotation at quarterback for this weekend’s game at home against Northern Illinois. Bret Meyer has started the first two games and Austin Flynn has also played in a victory over UNI and a loss at Iowa. He says both have done good things, although he says both have room for improvement.McCarney expected the defense to be much improved this season and that has been the case through two games. He says they’re playing more guys and have more depth. He says the defense knew last year they played well at times, they just needed a little more support from the offense. McCarney says he stayed with the defensive coordinator and now they’re leading in some defensive categories.McCarney says they no longer plan to redshirt Iowa City West product Greg Coleman who entered preseason workouts at running back. He will play this weekend at fullback. He says Coleman is a Big 12 football player that deserves to be on the field, but he says Coleman needs more work and they need to get him on the field.
