There is no question Stanford's David DeCastro will be picked within the draft's first 20 picks. The only question is where the offensive lineman prospect will be picked.
SB Nation's bloggers mock draft has DeCastro being picked at No. 14 by the Dallas Cowboys. Blogging the Boys, SB Nation's Dallas Cowboys blog thinks the Cowboys should pick DeCastro because of the team's lack of youth along with the overall need for stability within the offensive line:
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.
Interestingly enough, the Cowboys did not extend a pre-draft visit invitation to DeCastro and could possibly not be considering the draft's top offensive lineman prospect at all.
Another intriguing possibility is the Seattle Seahawks drafting DeCastro with the No. 12 pick. DeCastro grew up in the Seattle-area and played at local football powerhouse Bellevue HS. In one of his mock draft updates, SB Nation's NFL writer, Ryan Van Bibber had the Seahawks taking DeCastro.
