Give Valuev the power of Wlad and the workrate of Vitali and you have unstoppable Heavyweight at the moment.
I seen him in a live fight in pittsburgh a couple years back, his hand speed is amazing, especially his jab. I think he's just a notch under an 02 Bryd type speed, but I think Chambers jab definitely got more pop.
Mayorgas balls, Roy Jones's ass and legs, Oscars face, Mosleys eyes and personality and Floyds stomache :yep
Mayweather's handspeed is pretty much equal to Judahs, his chin has never been cracked and he hasn't lost yet atsch :-(
I'd give Wlad Mcall's chin and Ali's stamina. Keep everything else the same and I can't imagine any heavyweight in history beating him.
No, Roy Jones in his prime didn't need a great chin and there is no evidence to suggest that he didn't have a good one. The best ever fight would be Prime Sugar Ray Leonard vs Prime Sugar Ray Robinson. Tell them both that there families would be killed if they lost and ring the bell :yep That would be unreal.
