At the age of 40 Stevenson has next to no chance IMO, surely that gauntlet is too tough he has to age eventually. I also give Kovalev little chance, he seems too mentally fragile Bivol or Beter or even Alvarez as an outsider IMO
Gvozdyk or Beterbiev would be my pick. Stevenson too old, Kovalev deserves to be favourite but I suspect that someone more hungry will pull it off.
