I don't really think it is up to the Packers. If you were a young, raw talent at CB, without the benefits of a high profile program in your history, would you want to choose Green Bay as your best chance to land a roster spot?
We are so deep at CB that I wouldn't doubt he is looking at other teams to sign on with, trying to get an offer... with nearly every team already loaded up to 90 going into camp. He'll land somewhere. I just doubt it will be GB after looking a bit more at the situation.
