At first, it didn't seem like there was anything to see here — just another abhorrent video of a Dallas Cowboys fan knocking out a Philadelphia Eagles fan with one violent punch. This came two weeks after an Eagles fan dropped a New York Giants fan with an equally vicious right cross. A bunch of moronic NFC East fans in the circle of lowlife doing what no human should do to another. It's despicable, really.
Then came this revelation, courtesy of TMZ and Deadspin: That Cowboys fan is really another Eagles fan, and the guy he knocked out was his brother.
