So how is receiver Javon Walker repaying the Oakland Raiders for taking a leap of faith on him, giving him a big pile of guaranteed money despite concerns regarding lingering knee trouble?

By showing up for offseason workouts out of shape.

Adam Schefter of NFL Network reports that there are concerns about Walker’s conditioning.  In March, Walker signed a six-year, $55 million contract, with $18 million in guaranteed money.

If it’s true that Walker has decided to let himself go, perhaps he was influenced in part by the team’s misguided effort to spread misinformation about the true value of Walker’s deal, after the Raiders faced some immediate criticism for paying Walker so much money.  Typically, NFL teams will stand silent even when a player or his agent are overstating the terms of a contract, in order to ensure that the player remains happy and content.  It’s unprecedented (with the exception of Walker’s case) for a team to quibble inaccurately with the terms of a contract that a player has signed.
