In Arrington's contract with the Redskins, they failed to read the final copy of the contract before having Arrington sign it. In the final copy, there was a 6.75 million roster bonus REMOVED from the contract by the Redskins, though it had been in previous versions.
When Arrington went to collect, the Redskins were like "WTF are you talking about. You're contract doesn't include that." And the Postons went scrambling. The Postons tried to blame the Redskins for altering the contract. However, the Redskins positions was, "You didn't read the final version? Tough. Your fault. Not ours."
