Jacobs is the top rated WBA contender who would make some sense around in early to mid 2018 as Brant, Canelo and Lemieux aren't going to be available in one way or another in all likelihood (assuming Jacobs beats down his tuneup). I kind of doubt Bob wants Murata's introduction into the States to be against someone of Jacobs' caliber, though, and I wouldn't be surprised if Jacobs wants to pursue the Saunders/Lemieux winner so as to really force the fight between the Golovkin/Canelo rematch winner (God willing it happens this May as it should).
