I think you just like saying controversial things to troll and to get a rise out of people. Ennis was getting hit often by the likes of a 35 year old Avensyan, Duran at 37 was putting on a defensive masterclass rolling with punches against a huge Middleweight who had just KO'ed Thomas Hearns in Iran Barkley.
Ennis is not a defensive wizard like Benitez and Ennis does not use lateral movement like Leonard he stays in the pocket. Why you think either of those 2 fights are relevant when Ennis fights nothing like either of those fighters is baffling just like pretty much all your takes.
You realize that Duran started his pro career in 1968. By the time he fought Leonard he had been fighting 12 years and had 72 fights. Not in his prime.
