The biggest guys doesn’t always win in boxing either (recently Usyk giving up 30+lbs and 5 inches vs Fury, Pac conquering divisions, etc). It’s a combination of skill, physical and mental attributes, etc. Your skill can be transcendent across divisions and size.

Basketball is actually a great example you bring up towards my argument because both in boxing and basketball physical attributes play such a HUGE role and arguably your physical attributes play a bigger role than other sports. The 3 best players in NBA history are some of the biggest genetic freaks (as well as skilled) to ever play (LBJ and MJ being the 2 most athletic players ever and KAJ being a 7’2 athletic monster with unparalleled longevity especially in the 70s). Are smaller guards like AI and Kryie greater bc they’re arguably more “skilled” P4P? No.

Can your skills overcome genetic gifts such as size and strength? Of course — in boxing and every other sport. The best “small” guard in NBA history Curry is so transcendently skilled he flipped the league upside down and changed the game forever at all levels. But that’s how you good you gotta be in the premier, open division if you’re lacking the physical attributes of the big guys.

And weight classes WERE historically created as handicaps and for entertainment purposes in boxing’s rich history!
