If we had to characterize it, we'd say that Albert Haynesworth and Redskins fans have a hate-hate relationship. This is what happens when you sign a $100 million contract and pretty much quit on the team. Haynesworth lasted 20 games in Washington before the organization traded him away for, among other things, lethargy:

Two days later, he told TMZ, "Most Redskins fans are the nastiest I've met and the most ridiculous in the way they act. They couldn't get any ruder."

Not helping: Haynesworth has previously warned players -- both currently on the Redskins roster and those being wooed by the team in free agency -- that Washington was a terrible place to play. In response, DC radio host and former Redskins tight end Chris Cooley once called Haynesworth "an awful human being," and said the front office made a "terrible decision" by signing him.
