If they would have received a compensatory 3rd rnd pick if they lost him in free agency anyways why trade him for only a 3rd rnd pick? So they get maybe 15 picks earlier in the third round but don't get him for the final 12 games?
Whatever, awesome to see Moss back in a Vikings uniform, hopefully Rice will be back before seasons end, Harvin in the slot, Peterson in the backfield. Awesomeness.
