Per Charley Walters at Twin Cities Pioneer Press:
I don't know why this means Gaines Adams falls magically to the Vikings. Shouldn't they have to pay like everyone else? If the Vikings want Gaines Adams they should have to trade up with us to get him!
Implicit in the above blurb is that the Vikings are interested in the pass-rush specialist, that he might fall to #6, and that we might choose him at #6 -- otherwise why would trading down affect the Vikings at all? If the above is true, then Brad Childress needs to start thinking about what he's willing to offer us to move up a spot to get his guy. Per this Draft Value Chart I'd say that's good for a 4th round pick.
Something about counting chickens...
