JaMarcus Russell
Russell is one of the worst draft busts ever and sends shudders down the spines of Raiders fans. Oakland drafted the LSU star after a star turn in the Sugar Bowl. They thought that he would be their franchise quarterback but things started badly. Russell held them to ransom until they agreed to a rookie-record $60 million contract.

But the Raiders became the biggest losers because he didn’t earn his money. Russell had notorious weight problems and didn’t take his opportunity seriously. The Raiders even sued him because they wanted to make some of his contracts back. It was an unmitigated disaster and remains the stuff of infamy (via USA Today Sports).
