You wouldn't be able to shop him Jacob. He has a no trade clause. What you'd be able to do is tell him "why don't you choose a few contenders you would like to play for" and then if one of them makes a good offer you honor that by moving him.
Also if and when AD wants out the Rams will accommodate him. They're unlikely to not trade him in that scenario, because the moment contenders know he's on the market I'd imagine there's gonna be interest. He's not the old AD any more but he's still better than most.
