The Cowboys believe they are out of the running for Raiders' free agent cornerback Nnamdi Asomugha.

According to ESPN, the Cowboys officials believe they are a long shot in the Asomugha sweepstakes.

The Cowboys are in need of secondary help and may look instead to the services of Ike Taylor, who won't be as expensive as Asomugha.

If the Cowboys were going to add Asomugha or any premier free agent, they would have to work around any potential salary cap that would come out, since they will likely be close to the cap with all their draft picks signed.

Asomugha has made $15 million the past two years with the Raiders and would command at least that much in any new free agent deal.

Besides the Cowboys, the Philadelphia Eagler, Baltimore Ravens, and Detroit Lions are interested in the services of Asomugha. The Raiders would also like to resign their free agent.

Asomugha became a free agent earlier this year when his contract was voided due to failing to achieve certain incentives and the contract also prevented the Raiders from putting the franchise tag on him.

The 29-year-old corner back may be the top free agent this year as one of the league's premier cornerback in his prime.

The NFL and players are currently in a labor dispute and any free agent signing will be under a new collective bargaining agreement.
