I think that the 'look back' is completely failed for ISU and I would like to see them go back to the huddle and then go up to the line of scrimmage and quickly get the play off. Team are just not fooled by the changes made in the lookback and the defenses are adjusting quickly to the any changes that ISU makes. If they are going to keep the look back, then once in a while go up to the line of scrimmage and run the initial play. With the look back defenses get lots of time to look at the offense, who is on the field, etc., so it is hard to surprise anyone.
