Reason he might not: Helu has been excited for free agency and if he receives a good offer elsewhere, he'll be gone. It's not like there's a ton of competition with third-down backs -- New England's Shane Vereen will be pursued hard, no doubt (though could re-sign with the Patriots). Reggie Bush will be an option for some teams. Helu's third-down numbers are better than C.J. Spiller's.
John Keim: They'll enter free agency with at least $25 million in salary-cap room, which is plenty of space to get started. So there's no urgency to release anyone else at this point. They've done this in the past, where certain players are kept only to get a pay cut later in the spring (Josh Wilson, 2013). I would not be surprised at all if they cut more players later. Let's say they want Mike Iupati and then sign him; at that point they could cut Chris Chester. But if they still feel Chester is better than others on their roster, then why release until you have a replacement? In other words, more moves could be made later depending on what they do.
Ties to the Redskins: Dallas' Anthony Spencer is a free agent; Redskins line coach Bill Callahan came from Dallas. But Spencer never developed into the pass-rusher many anticipated years ago. Dwight Freeney played in San Diego when new defensive coordinator Joe Barry coached the Chargers' linebackers. Freeney built his career as a 4-3 end and would only be good as a situational rusher. He also just turned 35.
