Werner and Piper had a good discussion about this on their pod the other day -- I am sure that the discussions between Adam (+ team) and coaches is going to be very frank and straightforward. At this point, there's no reason or use in being coy, and that means being crystal clear about what his role would be, how he'll have to earn it, how there will be no tolerance for being upset about his role, etc. And, importantly, if he does come back and still ends up "exploding" at some point, you can still just usher him towards the portal. Downside risk is relatively minimal -- if it works, great, and if not...well, he's familiar with how to do these things now.
Edit: I'm not sure what you classify as "devoted," but I don't think you're accurately reflecting how he played for our team this year.
