12. Albert Haynesworth
After signing the one of the NFL’s richest contracts, Haynesworth pretty much gave up. According to teammates he stopped paying attention in meetings, stopped trying in practice and it showed in his performances on the field. Apparently he even showed up to his first day of work massively overweight and out of shape.
Despite his lack of production on the field Haynesworth complained about the defensive schemes, his coaches and his teammates. He played with the Redskins for just 2 of the 7 yeas on that massive deal.
