I don't see how the Seahawks could've won if the refs made any different calls. They didn't lose any turnovers or TDs. They lost one 20 yard or so catch to Stevens and that's about it.

However: the "incomplete" pass to Stevens in the first quarter was a fumble. As was Hasselbeck's dive who was "down by contact" because someone touched his jersey as he was going down.

EDIT: I watched the game with people who hated the Steelers and were rooting for the Seahawks, and they had no complaints. In fact, they admitted that the refs screwed the Steelers over for those two plays that should've been turnovers.
