Other than a questionable penalty call for a low block, the game was fairly and accurately called, and I'm not a real fan of either team. The only conspiracy is in your own mind.
I'm not a fan of either team, but I can't see how you can say the game was "fairly and accurately called". Too many game-shaping penalties against Seattle where none was to be found, and a few non-calls (against both sides) that should have been flagged.
You cited the tackling-below-the-waist penalty, but neglected the non-holding penalty two plays before it that would have put the Seahawks on the 2 yard line.
I don't believe it was a conspiracy, but certainly it was an infuriating game - even with no "dog in the hunt".
