They resigned Everson Griffin and are reportedly still wanting to get Michael Johnson...so sounds like they'll have DE taken care of...
Robison has the other spot locked up and Griffen was probably the #2 DE available in FA. I'm very happy they re-signed him.
Good luck to JA. A contender will pay him a lot more than the Vikings would want to.
I don't see a need at DE anymore for the Vikings at all. I think this opens up the Vikings options a lot.
I'm thinking one of these scenarios happens, in order of how much I would like it.
1) Teddy B, Bortles, or maybe even Jonny Manziel drop to 8. I wouldn't love Manziel but I could talk myself into it. Teddy B would be a homereun at 8, Bortles would be fine.
2) Trade up a couple spots for Bortles or Bridgewater.
3) Trade down and take Carr or Mettenberger in the mid-late first for and stockpile picks in a deep draft.
4) Take best defensive player available and grab Carr or Mettenberger in the 2nd.
The Vikings are lucky that the positions on defense that they need can be filled in the 2nd and 3rd rounds, where they have 3 picks. They need LB help and they need a #2 CB. Also a NT. And on offense all they need minus QB is a G.
