One player I do think is GUARANTEED to be a Seahawk though- Denard Robinson. I guarantee you he's a Seahawk. He might even be a shocker pick at #56. I would bet you Seattle has a high 2nd grade on him- since his athleticism is 1st round level but he needs coaching up. He could be another Percy Harvin if coached up.
Pre-Harvin I would have definatly agreed with you. I still think its a possibility, and i'd still like the move, but I think he'd be a little redundant. Nothing wrong with redundant when its super athletic touchdown scorers though!
They might lose Tate in free agency next year. Plus they need a 3rd down running back. Robinson is already a really nice option as a Leon Washington type player, and he might be able to grow into being a Golden Tate type receiver. IMO, Robinson makes more sense today than he did pre-Harvin since Washington is gone now and Denard Robinson is more of a RB, IMO.
Nothing about Harvin/Robinson is redundant anyway. You could line up 2 Percy Harvin's and one Jordy Nelson type and have an amazing offense- which btw is exactly what Seattle is trying to implement. And besides that, Robinson would be pretty unlikely to play WR much in 2013. He'd start out at RB and work his way into a WR role after a few years of coaching up. He'd be a RB/KR that would also act as injury/FA insurance for Tate/Harvin.
Personally, I'd wait til the early 5th to get Robinson, but it seems the media is finally starting to figure Robinson out the way I did instantly, that he's a RB who might be a WR later, and that his talent/risk might vault him into the 2nd day of the draft. It might, and if Seattle picked him in round 2 or 3, I'd probably support the pick.
