I usually don't watch the Super Bowl but this year I did. It was quite entertaining. Especially if you were rooting for New England as I was.
Obviously Seattle's decision to pass on the critical play was debatable and it certainly didn't work out. But the level of criticism the Seattle coaches have received seems unreasonable. I doubt the claim that this was the worst play call in Super Bowl history. Instead it appears to me it was likely the unluckiest play call in Super Bowl history in terms of the actual effect of the play on Seattle's winning chances as compared to the expected effect. The level of vitriol does demonstrate why coaches are reluctant to go against the conventional wisdom. If they do and it doesn't work out they get crucified.
