I'd say usyk first, seems he is off to heavyweight and I would guess at a KO coming his way at some point, he seems pretty determined to move up fast too... Bellew could also win he seems to have something strange going for him..

Inoue second, top geezers around him and japs love to get into a a really hard battle, so there's a good chance of him losing and then. Coming back to KO... Top guy though going to be super hard to beat for anyone.

Then Crawford... I actually think Crawford is tip top, and Spence is his only big threat.

So usyk due to him going in with the really big guys.
