which of these boxers has the highest chance to KO vitali klitschko should they fight

Haye has power and speed. The others are either too slow or don't hit hard enough. Tua couldn't hit Vitali if he had a baseball bat.

I seriously doubt that there's a HW that can KO Big Vit.....but if there was anybody capable of rockin' Vit to sleep on that list, IMO it would be Briggs :boxing:

in my opinion if tua lands his best shot on vitali it would rock him and definitely send him to the canvas...cant be sure it will be a ko though

Briggs? The only thing he's in line to KO is the record for most fights in one month lol

David Tua wouldn't be able to close the gap with Vitali's longer reach. Tomasz Adamek really never was or is a one-punch knockout kind of guy. We already seen what happened to Samuel Peter. Haye stunned Valuev with one left hook which is impressive so he has the best chance. Can't really comment on the other guys.
