Dunbar is a locker room cancer, a malcontent who wants a top 5 CB contract he was not going to get in part because he has missed 14 games over the past 2 seasons. There was no way Rivera's locker room was going to include Dunbar (and probably malcontent Trent Williams) so they had to dump him with no leverage as the acquiring team was not going to give up a lot knowing now they have to come up with $15M/year to make an injury prone cancer happy.
imagine they would pass on Young but this COULD imply Okudah is their guy.
Or, they may have concluded that they can trade down to around #5 or #6 and still get Okudah. If they trade out, that team is most likely seeking a QB. They may also have concluded that the Lions are going to trade out for a QB or would take Young.
That would only leave the Giants, who could either trade out, take the top OT, or take Young if he falls, or Simmons if the Lions take Young.
If they traded back to #5, they get more picks and Okudah.
