Other than length, no other terms of the contract are available.
Stallworth brings more of a veteran presence to the Skins' very young core of wide receivers. And even though the dollar amount of the deal isn't out there right now, given that this is a one-year deal, it probably isn't a high-priced one.
Stallworth is only 30 and, if he stays healthy, can contribute the the Redskins offense. This could be a low-risk, high-reward type of situation for the Skins.
