Yeah, that was strange to see Usually a 3 man rush is a guaranteed to get a drive going. AZ must have had some excellent coverage guys, because even with all day to throw, no one was still open. As the announcer explained it, OL's will angle themselves one way to block, but then if the DL moves the other direction to chase the QB, what was a good block becomes holding since they are pulling instead of pushing, suddenly.
It was a fun game to watch. While you often see Team A go out to a lead, then the other team comes storming back, you usually then don't see Team A then come re-storming back and put the game away.
Scoring last night was 13-0, then 0-24, then 25-0. The runback for a TD by AZ was of course the spark, otherwise I think they'd have been blown out.
