Other than the TD call, the rest were judgement calls that are left to interpretation of the individual official. Each one of the penalties were strict interpretations of the rules. But to suggest strict adherence to the rules as conspiracy, sorry "gross incompetence", smacks of very sour grapes.
I know, it's not what you would expect, is it? Which leads to grumblings of...
And whose "bias"? Any proof whatsoever?
I'm afraid the evidence is all circumstantial. We haven't found the photos of the refs at a Steelers tailgate party, if that's what you're after. Given a bunch of sketchy judgement calls, that could just as easily have not been called at all (and which usually wouldn't be called), the refs overwhelmingly made the calls that would hurt the Seahawks the most while simultaneously ignoring obvious penalties by the Steelers. The two consecutive offsides come to mind, the second of which resulted in a sack of Hasselbeck. Or how about the egregious hold that allowed Parker to burn off his record-breaking run? Steelers can point to one or two things that didn't go their way. The lop-sidedness of what happened is the problem, not the fact that one or two bad calls occurred. This is what Seahawks fans----and most non-Steelers fans----saw during the Super Bowl.
