David DeCastro

Guard | Stanford

Perhaps the most NFL-ready interior offensive lineman in college football, DeCastro is a pure run-blocker. At 6-foot-5, 312 pounds, he's a steamroller and the reason the Cardinal averaged 207.9 yards on the ground this season. He is well-versed in zone and assignment blocking and is just as solid a pass-blocker. QB Andrew Luck was only brought down nine times this season. He's widely regarded as the top interior lineman in the upcoming draft class and is expected to pass on his final year of eligibility and leave for the NFL. Makes sense; his stock will never be higher than when Luck is wearing a Cardinal jersey.
