This is supposed to be a fight? It's an execution. Hopkins couldn't gain twenty-five pounds & beat Bert Cooper, much less the resurgent George Foreman. I would take Foreman from his first comeback fight to his last to KO Hopkins at 210lbs or so.
When George came back at age 38, the one punch he could still throw like a young man was the jab. His jab was BRUTAL in that comeback.
Old Hops relies a lot on strength to muscle around fighters, he wouldn't be able to do that with Old George. It all depends on whether he has the legs left to move for 12 rounds, if he does I could see him eking out a decision.. it's not like Old George was any kind of world beater.
He doesn't have the legs right now, at his current weight, let alone as an artificial HW. Foreman would get it done forthright.
indeed. Still................. I think that even a Heavyweight Hopkins would have a better chin than Michael Moorer and Moorer almost lasted the distance.
