I saw comments based on at least 3 different systems that claim to assess the value for draft picks.
the consensus was that the Vikings came out of the deal with some net value - but depending on the system, the net value was equivalent to a 3rd-round or early 4th-round draft pick. that was the net gain for what they gave up and what they got in return.
that is peanuts for moving down 20 picks in the 1st round.
in other years, (yeah, I know) that type of a move might have brought you a future #1 in return.
So, not a great start for the new brain trust.
PS. Packers go defense - defense with their two 1st round picks. No WR for A-Rog. Enjoy that contract, baby.
