In SB Nation's annual blogger mock draft, in which each team's selections are made by their respective SB Nation blogs, the Dallas Cowboys, represented by Blogging The Boys, selected Stanford guard David DeCastro.

The Cowboys interior offensive line was a problem last season, and with the release of Kyle Kosier at guard last week, the position is truly in flux. Dallas did pick up a couple of veteran guards in free agency, but the future of the position is still in question. Enter David DeCastro, who many scouts have said is the best guard prospect to come along since Steve Hutchinson. He's got every skill you need and is a fierce run-blocker. Blessed with agile feet, he's extremely good on the move, and in the Cowboys run-blocking scheme the guards are often asked to pull. DeCastro is projected as the kind of player you pencil into the starting lineup for the next decade. Dallas picked up their tackle of the future last year with Tyron Smith, they could do the same at guard this year with David DeCastro.

The Cowboys have had a problem protecting Tony Romo, which is evident by Romo's injury history, and the selection of the draft class' best interior offensive lineman could go a long way when it comes to shoring up the team's line. The Cowboys signed guard Nate Livings and Mackenzy Bernadeau in free agency, and with DeCastro they would have some quality depth at the guard position.
