If Uysk beats Joshua again, and Fury stays retired, who would be the next four guys he should fight?

I make a similar thread like once ever couple of months, because it is exciting for me. Anyway, I am going to couch my picks in what I think is a logical path, but you use any criteria you like.

Deontay Wilder. Vacant WBC belt.

Winner of Paint-Dry Parker/Joe Joyce. WBO mandatory.

Sugar Bob Helenius. WBA mandatory I hope. The alternative is Hunter rematch or Bryan, and Helenius is the best of a sorry bunch here. I include it because I think it will have to be.

Bivol/Beterbiev winner. Bivol just beat Canelo, who was talking about an Usyk fight, so why not pick-up that torch? We all know the history Beterbiev and Usyk. Heavyweight without Fury is a ghost town. Why not fight one of these fine fighters at an agreed 201?
