It is generally accepted that Jose Bautista played his last home game for the Toronto Blue Jays this past weekend (2017-09-24) since the Jays are not expected to pick up their end of the mutual option on his contract (too expensive given on-field results this year).
Assuming that happens, does he just become a "normal" free agent in the sense that he can shop around and accept an offer from any team -- including Toronto if they make an offer that is acceptable to him?
Essentially, does anything in the CBA or other MLB rules prevent the Jays from signing him for terms other than those outlined in the mutual option?
