In FOX Sports' Peter Schrager's latest mock draft, the Dallas Cowboys select Stanford guard David DeCastro with their No. 14 overall pick.
Signing Brandon Carr is a tremendous upgrade at cornerback for Dallas, but there are some who'll be clamoring the Cowboys to pick Alabama safety Mark Barron if he's still on the board here. The defensive backfield was the team's Achilles' heel last year, but the 'Boys could use a big mauler such as DeCastro on the offensive line. Guards got big money in free agency this year. Taking one with the 14th pick in the draft isn't considered too high anymore.
Picking up Carr in free agency allows the Cowboys to grab a guard in the first round to help shore up their offensive line. The Cowboys signed Nate Livings and Mackenzy Bernadeau, but the selection of DeCastro would put one of these guys in a backup role, providing more depth on the offensive line, which is always a good thing.
