DeCastro continues to climb NFL draft board

ESPN NFL draft gurus Mel Kiper and Todd McShay agree on one thing: The Pac-12 will produce four of the top-seven prospects for the 2012 draft.

Kiper's Big BoardInsider and McShay's top-32Insider have identical placements for their top-four Pac-12 players: 1. Stanford QB Andrew Luck; 2. USC OT Matt Kalil; 6. USC QB Matt Barkley; 7. Stanford OT Jonathan Martin.

All four of those guys could return next year because they have remaining eligibility. Luck and Kalil have already announced they are entering the draft -- Kalil on Thursday.

Barkley seems to be enjoying the intrigue. My guess is he and Martin will both leave, but more than a few folks think Barkley wants to stay, in large part because he is enjoying being the USC quarterback and knows the Trojans are a BCS bowl contender in 2012.

The biggest riser in recent weeks is Stanford guard David DeCastro. He's moved up to 16th on McShay's list and 19th on Kiper's. Most expect DeCastro to become a rare interior lineman selected in the first round.

McShay has Arizona State linebacker Vontaze Burfict at 20th and Kiper has him at 19th. Burfict's draft status will be interesting to watch, as his junior season in Tempe was mediocre to bad on the field and in the locker room. But he's a fantastic talent and highly entertaining to watch when he brings his A-game.
