Here's what intrigues me about Matthews: Apart from the great production he's had at each level he's played thus far (which I think is important - he's a player, not just a great athlete), he's a noted jump ball specialist and seems focused heavily on blocking. His college bio even points this out, noting he had "excellent height and the ability to battle a defender for the tough catch ... Has been an outstanding blocker in the run game." Those two attributes are big for the Seahawks, for obvious reasons.
