These four in my opinion had the best jabs in heavyweight history, all having different attributes, Sonny’s long powerful ram rod, Ali for speed etc. Who had the best?
If Foreman used his jab more I would pick him, his jab was lethal, but I’m going with the obvious Holmes
The best combination of speed and power was Holmes, so his jab was best overall. Fastest Ali Hardest would be Liston off your list and Foreman . Lewis had a very good jab as well P.Thomas J.Louis were also very good. M.Tyson believe it or not in his prime was good.
I wrote the best COMBINATION of SPEED and POWER was Holmes. It means his wasn't the fastest, or hardest. But the best combination of the two .
Wlad never dropped anybody with a jab like Holmes did. Lewis , Thomas , Holmes , Douglas dropped guys with jabs. Bowe landed more jabs on Holyfield than Wlad landed on Sam Peter.
