Of course just saying that doesn't make it so. It is so, independent of whether anyone says it. Truth is truth, and its veracity is not dependent on one or more proclamations as such.
Pittsburgh fans may say this is sour grapes. So throw out anything that any Seattle fan has to say. But I have never seen anything like this in terms of fans of the other 30 teams taking to the Internet and complaining about the result of a game. People who had nothing to gain from the Seahawks winning. People who picked the Steelers in many cases. Fans of the other 30 teams are not supposed to complain about the result of a Super Bowl. Something went wrong.
