The talk of the team not wanting him back is just Talk. Click bait.
You don’t give him a guaranteed three year contract and then the next year say no we don’t want you back when you’re on the hook for 100,000,000 in dead cap.
If he decides to play and see’s that the Packers really can’t field a true contender a trade can be made.
But any trade will be with Rodgers blessing above all else.
