IMHO, nobody would have beaten Roy at SMW. When Roy was young at JMW/MW, Nunn was exceptional, and Mike MCCallum was a genius IMO. They would have had a chance. I don't think Gerald would have beaten him, and I would only have given Jackson a punchers chance. I guess people will mention Hearns, Hagler and Monzon from earlier eras. I don't think Hagler and Hearns would have beaten him, and to be honest, I don't know enough about Monzon to comment. At LHW, Foster, Spinks and Moorer would have been great, hard fights. So they could possibly have beaten him. I can't comment on the old time greats such as Moore and Charles etc. But nobody at SMW.
I limit my picks to fighters born from 1940 and on. Going further in past could raise more names. 160 : Golovkin , Hagler , Nunn , Valdez , McClellan , 168 : Nunn , Liles , McClellan 175 : Tarver , Glen Johnson , Michalczewski , Maske , Spinks , Qawi , Charles Williams , Moorer pickem : 160 : Jackson , Hearns , Benn , Eubanks , Briscoe , Pavlik , Taylor , Reggie Johnson , Carlos Monzon (if it goes 15) , Iran Barkley , Robbie Sims , Edison Miranda , James Toney (if in shape) 168 : Hearns , Benn , Eubanks , Calzaghe , Taylor , Froch , Pavlik , James Toney (if in shape) , Barkley 175 : Nunn , Hearns , Dawson , Dany Green , Montell Griffin , Greggory , Franklin , Ellis , Barkley , Stevenson , Kovalev
You're an absolute joker! Most of the pick em's that you have listed are absolutely hilarious. You must have typed those names while laughing out loud. Kelly Pavlik? Jermaine Taylor? Iran Barkley? Montell Griffin? Adonis Stevenson? Carl Froch? Danny Green? Glen Johnson? Calzaghe? Hearns? All pick em's at the weights listed, while Roy was prime? :rofl
Liles. I don't think so. Nunn at 168. Probably not. Danny Green pickem at 175. No. Remember wer're talking about prime Roy. Nunn at 160 in his prime is one guy who might beat prime Roy. Also, Hagler could possibly break him down over the long haul. I also think prime Saad Muhammad would have a good shot. He was better and accomplished much moore than Michael Moorer at 175. I don't think Charles Williams or Henry Maske would beat prime Jones. Barkley at 175. Abolutely not.
Moorer probably wouldn't win. But a tall south paw with ferocious punching power, quick hands and Manny Steward in his corner.. Probably not the type Jones would be dying to get in the ring with.
