you can't even compare the fab four of the 80s to the current fab four (Floyd, JMM, Pac, P-Will). Fighters today are just much better for various reasons.
off topic-, Hagler would have gotten his ass knocked out if Hearns hadn't broken his hand in the first round. This is obvious to anyone who has seen the fight. Duran would have won his second fight with Leonard if he hadn't eaten a ton of steak and orange juice right before the fight. and as you mentioned Hagler actually did beat leonard. I'm just explaining why I think the fights betweeen the fab four sucked. the best man almost never won
