Seattle needed to go with what got them to the SB. I think the call was beyond stupid.
Then, to top it off, they jump offsides when Brady could not take a knee. That could have been interesting indeed. 2 points for a safety would have made it take a FG to win. Can't predict how that would have worked out, but at least give yourself a chance to win after the bonehead play. But, in the end, Seattle was their own worst enemy.
