As a Seahawk fan, I really have no interest in the Vikings, but as a Seahawks fan it is very interesting to see what they do with their first rounders. I've seen a lot mock having them go with a WR and a MLB.
But if I'm the Vikings, I'd really press the need for WR. Peterson is not superman, he did it last season, as in carry the Vikings but you can't ask him to do that every single game.
Vikes have a quality enough D to be good as is. I say they should take Cordelle Patterson or Justin Hunter with their first and then replace Harvin with someone similar in Tavon Austin. If both receivers can excel in the league, Vikes would be a dangerous team.
