Football: Should Broncos trade for another first round pick?

Word out now is that the Broncos are targeting Von Miller and not Dereus. I think they trade down if they can but Iv'e heard them trading down with the 49ers(they want Peterson) or washington(want Gabbert). In this situationt the Broncos would Target Fairly. I hope that they just stand put and take Dareus and the whole Von Miller rumor is simply a decoy.
