Zab by early ko. His straight left hand would find a home early on The Black Mamba's chin and end it.
i don't think Roger's chin could last long enough to find Zab's "at some point." he'd either have to find it early, or not find it at all. my pick would be the latter. Zab by early KO
Truly a lightning-strike type fight....don't blink as whoever's straight power shot lands first ends it. I tend to favor Judah simply because he starts earlier and is much more explosive early....and Zab needs less room to let his big left hand go. His footwork is also faster allowing him to get close to Roger quickly. Mayweather needs more extension on his big right hand and is a slower starter....and his right isn't quite as versatile as Zab's left (straight, looped or uppercut). If it DOES get past the early rounds - and it could; match-ups like this tend to go to decisions as both guys respect each other's power and try to box intelligently....it's Mayweather, IMHO. But all things considered....Judah by early KO. Peace.
