Stack as many cards in your favour, the more versatile you can be the better but it has to be done right. Being able to switch or shift hit will benefit you against some opponents both defensively and offensively. Just don't be desperate like Dillian Whyte coming out southpaw against Fury, basically saying to Fury "I know I'm totally out of my depth here might as well try it"
They ain't **** compared to Hagler. Crawford is decent, Fury has good southpaw movement. Most of them still have to prove it's more than just showboating against cans.
Hagler was the best at it. He just smoothly changed stances. His opponents didn’t realise until they were getting rammed with the “OTHER” jab and it completely ****ed up their game plan. And just when they started to adjust he’d switch again. Know what I mean?
