The only middleweight of the modern era that gives Hagler a good fight is GGG it would be similar to the Duran fight.
The thread starter saying GGG is an easy win for Hagler has a clear biased agenda. GGG in his prime is one of the most beastly fighters I've ever seen. Absolutely undoubtedly an elite fighter, with a granite chin, solid fundamentals, and bricks as fists. He had 23 straight knockouts between November, 2008 to September 2016, a record for consecutive knockouts. I have GGG - Hagler as a 50/50 fight.
One thing about haggle. I feel he was underestimated at the time as a puncher. Believe it or not he was perceived by the boxing media at the time as not a big puncher. Hagler hit very hard imo.
You're a biased turd who probably watches Dontaes videos NOBODY in history could beat GGG at middleweight convincingly. Simple as. We are talking PRIME ggg here when he looked unbeatable. The fights he started to looked declined in (Jacobs, Alvarez) he was 36 or 37 years old!! Hagler lost to Bobby Watts and Willie Monroe yet GGG wouldnt have a chance according to you. Sure! Haha.
