If the Pack does trade Rodgers it will be for a young guy who is under contract that will fill a role for at least 4 years, along with several picks, spread over 3 years. I see two 1sts as a maximum though.
Here's the kicker. If the Packers believe that the team who gets him will end up near the top of the heap over those years, the number of picks will go up. If they figure they're still going to lose a lot, and the picks be in the top 10-15, the number goes down.
Nothing is cut and dried on any deal they make.
