So obviously, boxers are better at boxing, duh. Khabib vs Floyd, Stipe vs Tyson Fury, and other fights being thrown out, I think its silly, and the boxer will win 99 times out of 100. (if anyone disagrees, please explain in comments)
My question is, would size advantages even out the playing field and even tip in favor of an MMA guy, and if so, how much of a size advantage would the MMA guy need? In the build up for MayMac, Dana and others kept saying how much bigger Conor was, and could his power give Floyd problems. Well, Floyd ate his punches like candy. Almost no effect it seemed like. So here are some hypothetical matchups.
Who would win, how and why? All fights are open weight, boxing rules, 10 rounds, 3 min each. All fighters in their prime.
1. Manny Pacuiao vs Israel Adesanya
2. Canelo vs Rumble Johnson
3. GGG vs Anderson Silva
4. Roy Jones Jr vs Francis Ngannou
5. Floyd Mayweather vs Fedor
