DLH has the best left hook. Mayorga said it was the strongest punch he's ever felt. It also took Vargas out completely. He KO Paez and Leija in two which is yet to be done and will not considering they are retired. During RJJ reign in a couple of his fights the commentators would refer to RJJ left as an Oscar-Like left.
Oscar left hook is a combination of an uppercut and lefthook alot of the times, I seen RJJ throw a similar punch is a few of his fights.
Out of the fighters you listed, Trinidad. Of all time, I'd say Joe Frazier The best left hook KO ever - either Foster-Tiger or Robinson-Fullmer
To the body: Cotto To the head: Hmmm....tough to choose between Oscar and Tito. Although Tito has more power, I've seen Oscar shorten his left hook up better than I have Tito.
U almost feel Cotto's left hook to the body when u see him on tv so ill have to go for Cotto but Oscar and Tito are not far behind.
ODH could get off with his left hook in any position from any angle with power.. Tito had the perfect high shoulder left hook that would take your head off. But ODH could just rip it. I say ....................................Tito..since we are talking perfect.
This is an easy one i think out of the listed, De La Hoya. Like mentioned above he put Mayorga on his ass first round with a good connecting left, i'm sure Tito connected with a left early that couldn't do that to Mayorga in their fight. Some may argue it only put Mayorga on his ass like that because it surprised him but i disagree..
Tua, Frazier, and Tyson had great left hooks. Can't forget Tito either. Cotto now also has a hell of a left hook.
Bull****. When was the last time any fighter, especially a HW could throw a planted full power left hook as well as a hook disguised as a jab like Wladimir does? I swear he starts by throwing a jab & then turns it into a hook better than any fighter I've seen. It's really 2 different types of hooks that he throws & he's a natural with it. If you don't see that you're not watching closely enough.
