I don't think he would have done. Either way, GG won't get the credit that Marvin did. You also have to note that Marvin used to often weigh in at around 157, in the days of same day weigh-ins. GG would have been much bigger and heavier against Brook.
I'm a GGG fan but I think JR at 168lbs would potentially knock him out. GGG is not big enough to be a 168lb fighter, Canelo is a midget in the MW and won't rule it outright.
I think Toney beats GGG at 168lbs as well. I think GGG beats him down at 160lb. He's just too good in his prime, with crazy power and non-stop aggression.
Duran had no power at 154lbs, none. Brook will have more power than him at this weight. Brook would school "the gifted one" as well. He's a light puncher.
Wrong, Spence gets too much credit already. He was p4p number 9 before the Brook fight. He's the chosen one.
Joe hogged a lightly regarded title for 10 years, racking up 21 defences which impressed you. His main rival at the time was Ottke. Ottke didn't want to fight Joe. Obviously, that wasn't Joe's fault. But when he knew that Ottke wouldn't unify, that's when he should have made the move up to LHW. That was in the early 00's, when the likes of Lacy and Kessler weren't on the scene. But instead of moving up, he continued to literally starve himself to make SMW, in order to rack up defences against mainly low level opposition. But instead of criticising his actions, you praise them because again, the numbers impress you. Like you've said above, after clearing out their division, a fighter is obliged to move up. Yet Joe had no intentions of doing that. Yet you class his dominance over a weak division as a bigger accomplishment than what a guy like Mike McCallum did.
That's all well and good, except GG is obviously a completely different fighter to those guys. He's obviously not a slick southpaw with a 77" reach and great reflexes like Nunn was. Neither is he the technition that Mike was, or the freak that Roy was. Just because THEY caused James huge problems, it doesn't mean that GG would have done. GG has great attributes. But from Jame's perspective, a fight against GG wouldn't have been as difficult stylistically. I'm not saying a fight against GG wouldn't have been difficult, but he wouldn't have been dealing with a faster guy, a taller guy, a guy with a bigger reach, or a guy who was incredibly hard to hit clean. Here's the thing: GG couldn't replicate what those guys did against James, but James could have replicated what Jacobs and Canelo did against GG to cause him so many problems.
Starve himself, what nonsense Joe was only 5'9. Starving yourself is what Ward did, he was a LHW getting down to 168lbs to have that clear physical advantage over his opponents.
There is no nonsense. Joe isn't 5'9. He had a walking around weight of around 192-196 pounds. By his own admission, he literally had to starve himself to make weight. He used to go through hell. Why did he do that, when he could have targeted better opposition at LHW, which was a more comfortable weight for him? I think we know the answer.
