Every man has his breaking point and looks for a fresh start. It wouldn't surprise me at all, personally.
Tre basically said "I don't know what the future holds but sometimes a fresh start is best for everyone." It's Bundy so he's dumb, but I don't think he'd say something like that without knowing what the new regime thought about the player. I think it's possible that Mo has made it very clear, at the very least, that he's very open to a move. Maybe not a formal request, but yeah, he hasn't looked happy in Toronto in a good while.
