Manny Pacquiao and his straight left that he seems to land at will. Even though JMM later gave him a great fight and figured it out, that first round I was amazed how many times that left landed.
Carlos Baldomir- Straight Right. It looks lazy and weak, but it always lands and even found it's mark against Mayweather (see sig), and it always does damage (Judah, Gatti, Clottey)
corrales - left hook
de la hoya - left hook
zab judah - straight left
miguel cotto - left hook to the body
trinidad - left hook
hopkins - straight right
Thomas Hearns and his Incredible Right Hand.
DITTO!! it was easily the best right hand ever!! incredibly fast and powerful
his jab anmd left hook were also great punches
i love frasiers left hook because he used it so well
