My guess is that Cook has been working as the backup during the bye week. No way he could come in there that cold and be that effective and calm unless he had been practicing at QB. But, if that's the case, how did they keep it a secret from everyone? At any rate, even if Huebener comes back, we now DEFINITELY have our legitimate Wildcat Formation QB…one that can throw effectively out of that formation! LHCBS is truly a genius.
