IMO the option lacked the quick strike that many of today's offenses have. It was proven when NU would get down by more than a touchdown or two and were unable to come back. Yes, I know that we had some big runs during the option time and some big passes, but it took time to tire the defense and put them to sleep and then, BOOM a big run would happen. The WCO gives us the option to get down field in a hurry with one or two big pass plays.
