Just my opinion, but Manning rarely had a QB that could make the throws necessary to beat that defense. Or the WRs to help do it. The only QB that had the combination of arm strength and accuracy to do it was Park. And he lit up that defense. Yes, I know that Purdy is included in the list of guys that couldn’t make that throw.I'm hoping Scheelhaase has figured iowas zone d better than Manning did. There's ways to beat that system, we just never tried them with Manning.
