The Raiders are scheduled to hold a mini-camp this weekend, but don't look for JaMarcus Russell (pictured) to be a part of it.

In fact, he could be off the team's roster by the time it starts.

Speculation persists that Raiders owner Al Davis is prepared to part ways with the No. 1 overall pick from the 2007 draft, this just days after the Raiders traded for Redskins quarterback Jason Campbell.

Russell has made just over $36 million in his three disastrous seasons with the Raiders, and his career has been marked by poor play, excessive weight gain, and questionable work habits.

At this point, it's time to stop throwing good money after bad and say goodbye to Russell, who is still only 24 years old and theoretically has a lot of years ahead of him to make good on the team's investment. But Russell has shown little willingness to pay the price to become a top-flight quarterback. Heck, he isn't even doing enough to be considered a mediocre quarterback.

Time to end it here and let some other team take a chance on Russell. And time for Ryan Leaf to get ready for the day when he's no longer considered the biggest draft-day bust in NFL history.
