I am a fan of neither team, however I did think the steelers would win. that said I find it interesting that you think they played better. I thought that the seahawks played better, and that the steelers just "got lucky".
I disagreed with the refs on a few calls, but those went as much against as for pittsburgh. and the fact that I disagreed with them doesn't mean they were wrong, just that I disagreed - they know thier job pretty well or they wouldn't have been there.
When push comes to shove...you gotta trust the NFL system for choosing the officials.
I understand they used to keep ref squads together. Now they are composed of the highest graded officials from all crews.
