Stave got, if I've remembered correctly, about 280 yards of passing in windy Madison. Seems to me Iowa has to scheme more shorter, more unexpected throws. And CJ proved he could get it there even when Iowa was against that wind... although most of the time he overthrew.
Illinois' run defense isn't as stout as Wisky's. Just to prevent 8 or more men in the box, throw and be successful. Doesn't have to be for huge gainers.
Why do some coaches prefer play action passing to shorter passing to a whole slew of receivers? Surprise!
