Mocking The Draft's Dan Kadar and SB Nation's Ryan Van Bibber differ - slightly. Both have updated their NFL Mock Drafts and the player Kadar has the Seattle Seahawks taking is taken in the spot that follows in Van Bibber's mock.

Kadar has the Seahawks taking Stanford offensive guard David DeCastro to help solidify an offensive line tasked with protecting quarterback Matt Flynn and providing running room for running back Marshawn Lynch. In steps DeCastro into a hole made by the release of Robert Gallery. But Kadar also mentions Baylor's Kendall Wright and Notre Dame's Michael Floyd as possibilities in this spot.

And that's exactly where Van Bibber went with his prediction. Van Bibber has the Seahawks taking Floyd with DeCastro going to the Cardinals a pick later. Van Bibber's reasoning?

"Matt Flynn was used to having a handful of wide receivers to target when he was with the Packers - in practice anyway. Seattle will want to give him as many options as possible, especially with Sidney Rice's health a continual question mark."

So, wide receiver or offensive line? We'll know soon.
