If Fury sticks to his word ( I doubt it), Usyk is sidelined due to the war, and Wilder has retired Then Hrgovic, Joyce will become the top guys. Dychko, Jalolov, Makhmudov, Gassiev could become players too.
He is less movement than Usyk who has good chin very good skills and great stamina. The upper limits of Sanchez chin and stamina have yet to be tested. Sanchez lost a lot and just has 1 KO in 43 wins as an amateur. He can box yes, but will he stand with a good puncher who has skills or will he play it safety first?
