GGG KO's all of them. None of those guys are real middleweights and the one that is the closest to middleweight has chin issues. Leonard might last the distance.
160 duran does not beat GGG man, cmon, stop it. Duran is the far better overall boxer, and moved up in weight etc, but Duran is tiny.
How?? Duran is too small and his chin isn't good at middleweight, Hearns KO him, so will GGG. Hearns-He is way too chinny to take GGG's power punches. Leonard- He can run but he can't hide. GGG lands a bomb and SRL falls face first.
