Position: Defensive end
2013 salary: $715,000
Summary: Acquired in a trade from Kansas City the week before the season began, Jones played in only seven games with five tackles, three pressures and a pass deflection on defense. He also had five special teams' tackles. He missed nine games because of a groin injury that eventually required sports hernia surgery.
Why keep him: Maybe you've heard the Cowboys need defensive linemen? Jones has the added benefit of being able to cover kicks and punts, which is not a trait you usually find in defensive ends. Before the injury he was doing well in a limited role, so maybe he could be a rotation player in 2014.
Why let him go: He has 1.5 sacks in seven seasons. You would like more production than that, even in a backup. He turns 30 in December and getting younger and cheaper is always a better option for a team in cap trouble.
Best guess: Jones will be able to test the market, but he is looking at another year of making the minimum wherever he signs.
