@ Dubblechin - you are precisely right. I tried having the same conversation a couple of weeks ago on a Conn thread or something and most get it without having to think about it, but there are some who refuse to except the reality.
not referring to you bud, just making a general statement to those who know in their intellect that Bigger men are Bigger men, yet won't except that in past era's they would have fought in heaver weight divisions, not lower ones than their more natural big men weights
I'm not saying that's necessarily false, I'm just saying the reasons I've heard for why this is supposedly true are very unconvincing to me. There may be more convincing reasons that I've not heard.
Proof? He's the guy who weighed in! (LOL) Don't be an idiot. I provided video proof of JACOBS telling you how much JACOBS weighed when he stepped in the ring with Golovkin. Jacobs also weighed in the morning of the Canelo fight, and he weighed 173 ... and had to pay Canelo $750,000 ... $250,000 for each pound he was over the agreed upon 170-pound "morning of the fight rehydration clause." By comparison, Michael Spinks weighed the same 173 the day of the fight for his light heavyweight unification with Qawi. And Jacobs still had 12 hours to go from his morning "rehydration" weigh in to his fight with Canelo at like 11 p.m. that night. How many pounds did Jacobs add to his 173 in the next 12 hours? It's not the 70s and 80s anymore. None of these middleweights are entering the ring at 159.
The only guys I can fathom having the power to stop Hagler at 160 are: Ketchel Fitzsimmons Robinson and maybe RJJ Robinson managed to stop LaMotta who was probably Hagler's equal in terms of punch resistance but Hagler was a better boxer so I would pick Robinson to win but not by KO or TKO. Jones never fought anyone as good as Hagler at 160 and wasn't quite as dynamic in that division as he was at super middle so if he wins, it's on points too. Ketchel and Fitzsimmons clearly had the power to knock anybody out but I think Hagler head to head would be a tough ask for either of them so I'm going for the Marvelous one to win those. So no knockout there for either of those guys.
You might get some sharp shooter like Ray Robinson, Roy Jones Jr or Thomas Hearns opening cuts serious enough to force a TKO but I can’t see anyone winning by physically knocking him out. It would be quite a feat just to knock him down.
