name the best jab at heavy weight

[Panamaniac]

1. Holmes
2. Ali
3. Liston
4. Louis
5. Foreman

[Dynamite76]

Probably Holmes, but Ali, Liston, Carl Williams, Page, and Thomas also had great jabs.

[BlueBaureit99]

without having read the other comments:
Ali
Larry Holmes
Both Klitschkos
Lennox Lewis

and guys like Tim Witherspoon and Carl Williams also had a great jab.

[Sugar Adam Ali]

holmes in my opinion

he could dictate the whole fight with that one-punch

ali had a great one,, lewis as well

[New England]

sonny liston, muhammad ali, and larry holmes.

my vote is for prime ali, but you could easily put liston in there. his arms were freakishly long, and his jab was a genuinely powerful punch.

Holmes best jab regardless of weight class

[New England]

Holmes best jab regardless of weight class

if you ask me who the best jabbers of all time are i'm picking a few HW. that's the weight class where they're the furthest aprart, where the jabs are the hardest, and a right hand at range can always end the fight.
