How is Pacquiao's a left hook when he is a southpaw? Anyway I like this one: http://www.youtube.com/watch?v=TMlsCc5v_ZY
i still voted for the floyd patterson ingemar johanson one because johanson gave the impression of being airborne and then when he landed the leg twitch trumps everything
To top it off, one left hook set Ruiz up, another lefthook KO, and another one nearly put him in a coma. Tua has the most underrated left-hook in boxing.
Maybe not the best ever left hook Ko but need to be mentioned. http://www.youtube.com/watch?v=hO_sWnawpU4
Those two left hook KDs are nice too. http://www.youtube.com/watch?v=nm5_XDWDoqY Generally the whole fight was a parade of brilliant left hooks from both fighters. http://www.youtube.com/watch?v=i7Ik24HGlKQ
Because throwing a hook from either your lead or rear hand is still called a hook. Most hooks on here are thrown with the lead hand, Pacquiao's just happens to be thrown with the rear hand. Either way it's still a left hook.
