Thinks about what you are saying.
What would happen in boxing if you tried to streamline a 6-1 fighter to a Championship fight?
He wouldn't get there because he would get absolutely fucked up before he even got close.
Brock fought a former world champion in his second career fight. Then he beat a solid fighter in Heath Herring and then beat the UFC HW champ in his 4th career fight.
This could just not happen in boxing lol. You can't even try to come up a logical hypothetical for it. Brock was a NCAA champion wrestler than didn't even train wrestling for years. Dude did WWE and tried to play football. I highly doubt he was practicing anything but WWE grappling for litterally years. Then he takes up MMA and beats the champion after essentially not even training an MMA base since he was in college.
What would the boxing equivalent to that even be? It would be like if Deontay Wilder beat Tyson Fury in his 4th career fight lmao. And
Wilder is pretty much the only boxer I can even think of that started that old.
