IRVING, Texas -- The Cowboys have youth at the wide receiver, center and running back spots.

Receivers who are on the market -- such as Patrick Crayton, Plaxico Burress or Jerheme Urban -- could make for good No. 3s.

Available veteran running backs who could be of interest include Patrick Cobbs and Cedric Benson.

The market for a center seems weak with Jason Brown and Scott Mruczkowski being the best of the bunch.

Don't expect the Cowboys to sign any one of those players any time soon.

"I don’t know at this time until we see where we are at these OTAs and minicamp and see where we are at training camp," Cowboys owner/general manager Jerry Jones said. "I like what I see, and we’re going to get what we bargained for with our free agents and our veteran free agents in the offensive line."

The Cowboys have signed veteran players this offseason: Brandon Carr, Brodney Pool, Nate Livings, Dan Connor and Mackenzy Bernadeau.

Carr received the biggest contract, $50.1 million over five seasons. Livings and Bernadeau signed for a combined $30 million.

The center position might be an issue if Phil Costa, last year's starter, struggles, but the Cowboys are impressed with him thus far.

"I know just the initial work, and that’s questionable without pads on, (offensive line coach) Bill (Callahan) likes what Costa is showing us out there at center and that’s important to me," Jones said. "I think some of the things that we’ve done with the potential coming-on of (offensive lineman David) Arkin and the way these young guys are looking. All of that looks like that we may have found some answers there in the middle for us that when we ended the season, I wasn’t so quite sure about. So I think all of that if it continues to come together from my perspective will make me quit looking other places."
