The worst contract in the history of free agency is no longer active. The Raiders finally cut Javon Walker Monday and dumped defensive end Greg Ellis while they were at it, according to ESPN's Adam Schefter. Walker was named the biggest free agent bust ever by the NFL Network, and we can't disagree. His contract was particularly egregious because it was obvious in 2007 Walker had nothing left physically. The guy was benched for Glenn Martinez in Denver. (I actually wrote a post at the time in my former life calling it the worst contract ever. Blind squirrels, nuts, and all that.) Oakland paid Walker $21 million over the last two years and got 15 catches in return. He may wind up in someone's camp this year, but it wouldn't be a surprise if he's played his last regular season snap. Ellis actually started his Raiders career well enough, but knee troubles slowed him down late in the season.
