If you recall, right after halftime, the dynamic duo of Joe Buck and Troy Aikman pointed out that the Niners should have been flagged for 12 men in the huddle. And, both the Panther and Seahawk supporters were using this as ammunition to show how the Niners had the refs in their favor.
Well....Matt Maiocco had a good article explaining why it wasn't, in fact, a penalty. In short, as the play clock had not started yet and the ball was not marked "ready for play," then this isn't a penalty. Where was Fox's go-to-former ref Mike Pereira to explain this one?
