i saw a screen pass that shat on that
It's a combination of both. Receivers had issues getting open and the o-line was only giving Cam 1.8 seconds to react. I mean, after a full quarter of watching the opposing coaching staff send 5-6 rushers, you would think Shula would take advantage of Arizona's overaggressive playcalling with screens, underneath slants, uptempo sets/no huddle, etc. Nope.
