If Butler really wanted out of Chicago, he could let the Bulls know that, unless he is allowed to go to the team he wants (in this case, us), he plans to accept the QO and then leave after next season. The Bulls would still have the option to keep him anyway, and we would have to give up assets for them to not match/for a S&T. So it's *technically* possible, but I can confidently say that it won't happen
