Boxing Pound-for-Pound Rankings: Oleksandr Usyk leaves no doubt as to who is No. 1 in the world

Usyk put some space between he and his contemporaries in the race to the top with his latest win over Tyson Fury

If part of the very definition of the term pound for pound surrounds being able to defeat a variety of boxers at different sizes and weight classes, then what unified heavyweight champion Oleksandr Usyk accomplished on Saturday needs to be applauded even more than it already has. 

Usyk, a 2012 Olympic gold medalist who went on to becoming undisputed champion at both cruiserweight and heavyweight, was already considered by many to be the P4P king entering his rematch in Saudi Arabia against Tyson Fury. But when considering Fury's weight gain for their second fight, which Usyk captured by unanimous decision in a nip-and-tuck affair, the native of Ukraine might as well have been competing for the super heavyweight title.

With Fury entering at a career-high of 281 pounds, Usyk was forced to overcome a 55-pound weight disadvantage, which only added to the fact that the 36-year-old Fury was one year younger, six inches taller and held a reach edge of eight full inches.
