Just because you punches in bunches, fast arm-flurries, it doesn't make you one of the greatest combination punchers. The more important aspects to combination punching are creating and exploiting openings. Joe Louis didn't throw nearly as many punches than someone like Meldrick Taylor but he was a better combination puncher than him, although Taylor was very good too. I wouldn't be able to narrow it down to just five. Too difficult. Sugar Ray Robinson and Joe Louis take up two of the spots. Others like Mike Tyson, Roberto Duran, Evander Holyfield, Juan Manuel Marquez, Marco Antonio Barrera, Ike Williams, Julio Cesar Chavez, Sugar Ray Leonard, and numerous others can fight for the other three spots.
Excellent pick...while better know for his jab and heart, Larry was a clinical combination puncher.:good Not so sure about Ali though.
He could both flurry and throw real combinations with leverage and power with effectiveness. Pacquiao seems to throw a lot of flurries too, but manages to do it so well that it causes more power than most fighters do when they throw combos with leverage. Not all of his are arm punches or flurries though. He does all kinds of things from strange angles, it's crazy and pretty amazing.
