He'd school Tua and Vitali, especially Tua though Tua might get lucky once out of 10. Wlad and Ike are much tougher fights, i'd favour Usyk about...
116-113 Usyk.
Mercer UD.
Ali wide UD.
Arbachakov late KO.
Agreed.
Rosario KO.
Tszyu.
Ike late KO.
Duran UD.
McCallum would win about 8-4 in reality but Canelo would get the decision.
Leonard UD.
Only maybe Hagler and LaMotta could've taken that shot.
Eubank takes a beating but he has the chin to handle it G-Man then gases and Eubanks wins a UD or maybe stops him late.
I'd go for Holmes UD.
