Sorry, but I doubt it. They sit in front of their cameras for two weeks straight calling the Patriots cheaters, calling Belichick and Brady liars, and running New England's historic Superbowl run through the mud.
This is what will stick, because they decide what sticks and what doesn't.
When they're proven wrong, they won't look like buffoons, because, unfortunately, they're the media, and the media decides who looks like buffoons and who doesn't. Unless ESPN is going to run 24/7 stories about how stupid and wrong they were, there is nobody to make them look as idiotic as they are and deserve outside a few diligent message board posters, which isn't enough.
People like Jerome Bettis will still be talking about "deflated footballs in the AFC Championship game" three years from now, jamming it into Crygate conversations, regardless of the outcome.
The media is this nations omnipotent Master, no matter how ridiculous and embarrassing its members are, because, sad as it is, the masses are even more ridiculous, and even more embarrassing.
