sugar ray robinson had the best hook in history, it was hard, fast, accurate and versatile, he was known to throw 3 or 4 like a combination, not everyone does that you know and the kayo of fullmer deservedly has been called the greatest kayo ever. as far as the 90's and beyond, roy jones and delahoya get my votes, they are about tied, both had the kind of kayoes with the left hook that belong up there with the greatest ever. Lots of good ones though really, sugar ray leonard had underrated power in both hands but he damn near killed davey boy greene with a left hook. Of course, alexis and julio cesar chavez with those "gaucho's" . the left hook to the body was what eddie futch called boxings most important punch because "it makes the strong boys weak and the fast boys slow". Hooking off the jab is great but roy jones often just feignted a jab and lept in with a hook, and, he also just threw it without any feints at all, the griffitn rematch he just threw left hooks, seemingly with abandon until he damn near decaptitated his man. Delahoya did a robinson/fullmer imitation with the final knockdown of vargas but he had a lot of impressive hooks in his highlight reel, especially as a sub 140 pounder.
