There's no spin about it. What about the catch and fumble that probably would have been recovered by the Steelers but was incorrectly called an incompletion? What about the illegal block in the back laid on Ben after his second INT that went unflagged? Bad calls went against the Steelers too. And accusing people of spinning doesn't change the facts.
Seahawks fans think they got screwed. Pittsburgh fans say that the officiating didn't favor one side over the other. Fans of the other 30 teams think the Seahawks got screwed. Pittsburgh fans are wearing blinders.
