Deebo's play before half was certainly a game changer. but plays before half change the course of a game. Last minute TD's WIN them. If the Cardinals score there it changes the entire complexion of the second half. You can't just add 7 to their score and minus seven from the Steelers. The Steelers might well have lost, but they also might have become more aggressive and it wouldn't have come down tot he final play. Remember, they had competent assistant coaches then without Tomlin overstepping his knowledge.
