JaMarcus Russell, Oakland Raiders
Poor JaMarcus Russell is widely considered to be one of the NFL's biggest draft busts ever – and for good reason. As the first overall pick in 2007, Russell entered the league a hero, joining the Oakland Raiders who were hungry for a star. He left, however, after three disappointing seasons, and getting away with a cool $32 million in guaranteed cash. A sad addendum: with the NFL long in his rearview mirror, the former QB got the itch to return to the league last year and penned letters to various teams offering to play for free. Not a single one bit.
