Who had the fastest hands of all time, pound for pound? For me, it's Roy Jones Jr. It's not natural for a LHW to be able to throw combos like that.
Jones out of the ones I have seen. It made him invincible. Once that speed was gone in his late thirties, his lack of fundamentals left him a helpless victim in his eurobum exhibition tour. Several other fighters possess good speed but they lose other aspects of their ability when they utilise it. Khan is so fast, but he becomes linear and open to the counter of someone who times him when he does it. Yet Jones carried his full power and pinpoint accuracy with the speed he produced, and seemed able to make snap judgements fast during punching - it wasnt just his hand speed but his thought speed too was lightning.
Amir Khan has the fastest handspeed ever. Gary Russell's handspeed at close range is the fastest but not overall handspeed.
Man i dont know. I always thought Judah was fast af. Russell does stand out as one of the fastest Ive seen as of lately. Khan of in up there. Jones of course. At the end of the day all these names will be mentioned in whatever order.
