Too many to name....
Joe Frazier, Jack Dempsey, JCC, Trinidad, Oscar, Roy Jones Jr., there's too many great ones out there.
I love JMM left hook and head combo, he seems to be able to throw it from a distance which is hard to do without getting countered. The way he was hitting Katsidis with it was viscous.
Tyson had the fastest left to the body then to the head combo I've seen. Look at that combo that ends this fight. Frazier was just as good, if not better.
I agree with a lot of the previous mentions but I'd like to add a couple guys I haven't seen listed
Oscar De La Hoya had one of the best left hooks I've ever seen.
Mike Tyson had a tremendous left hook that he was able to put big men away with a single shot.
Not sure if Miguel Cotto has been mentioned but his left hook has always been impressive and is his best punch.
Def. Roy Jones, Floyd has a quick accurate counter left himself, Tyson had a devastating left hook. but you know who has the worse left hook? the one dude with left hook in his name Jeff "Left Hook" Lacy, is there video evidence of him actually knocking someone out with it?
how did I know someone would say this? lulz.
bunch of the best examples have been named
good stuff
gonna go with a few that haven't gotten the nod
they aren't the best with it
but they are some of the hardest ever thrown
donovan ruddock
gerald mcclellan (according to emanuel steward the g man knocked out over fifteen men with the same combination, right hand up top and the hook to the body)
floyd patterson
george foreman
