Wlad is a skilled big man, great execution, high IQ, excellent footwork and defense. Vitali is an arm puncher with good instincts and foot work; not even close to his younger brother in execution and overall skills. Jeff Mayweather trained Sultan was probably the most skillful heavyweight in recent years. Unforunately, became too saftey first and than inactive after the frustrating Wlad shutout. But excellent head movement, footwork, and fast combination punching when he put it all together.
Fighters tend to never be the same once they received the worst beating of their career. Chambers lost because of Povetkin's body shots that took their toll IMO. "Put him in with Chambers that beat Dimitrenko and he losses" is only speculation on your part. It's not fact. I suspect there's something more with the current HW division that's bothering you aside from your amateur assessment of their skills :hi:
Today's heavyweights are garbage because they start fighting in their 20's. Look at the few who are skilled and they all started young.
