Not one stinging shots but,who had the best jabs thrown to hit or block or pick off punches to set the overall tempo and other punches that they had,who could put their skills together the best off the jabs strictly on what they wanted to do? This one was tricky but I came up with this.... 1/ Tyson 2/ Ali 3/ Wlad Klitchko 4/ Lewis 5/ Holmes
In his second career, Foreman used the jab as a great mis-timer for his right hand. See: Moorer fight.
He had more of a limited skill set,usally a jab/pause straight right...who put together the skills more better after the jab,I think the above I listed do..
