GGG is being overrated a bit. To be honest. Many people could stop him. Even Julian Jackson could land a big punch. Hearns, Mugabi, Benn. Bit punchers.. Who knows. Roldan lands a big punch. I think Duran could do well against GGG. That style..
Lemieaux is likely the heaviest puncher GGG has ever faced and I would argue that Lemieaux' power pales in comparison to the likes of Julian Jackson, The G-Man, Hearns, Nigel Benn at MW, Beterbiev, Moorer, Mugabi, Edison Miranda, RJJ and then you have the likes of Michael Nunn who slept world class if not elite level fighters with a single shot like Kalumbay. Even Chris Eubank Snr. had a shed load of brutal, 1 shot, render unconscious KO's. Any of those guys, either through accumulation or perfect timing can, given the right circumstances probably KO anyone that ever lived in and around their weight. The Marvellous Marvin Hagler possessed the best chin I've ever seen.
I would take the Kovalev that annhilated Cleverly to give GGG a sustained beating to be honest. The Krusher was on a mission that night that would have been virtually impossible to deny.
Benn couldn`t stop Sanderline Williams and GGG is better than Williams wa in every aspect of the game, he is also better than Watson and Eubank were, both took Benn`s shots better than Benn took their shots. Duran didn`t punch as hard as GGG at middle.
It would take Hagler a lot of shots,he use to wear down fighters rather than blow them awway, he wasn`t a harder puncher than GGG was.
I watched his fights live so yeah I know Marvin style....I just stated he would KO GGG. Did I say with one punch???? Like WTF is wrong with you bro
