The answer should be a heavyweight as pound for pound can never ever be proved.

If you get into "can never ever be proven"(sorry for misquoting just couldn't being myself to write it the other way) then your only option is the current heavyweight champion. Because cross eras can't be proven either.c

Don't hamstring thought.

It's "bring" myself.

The answer is Ali.

Haha

James Toney.

Consistent.

I'm going to say Robinson, but I wouldn't argue with anyone that said Armstrong or Ali.

I have pep above Armstrong. Pep is unbelievable. But I wouldn’t necessarily argue either way. Again, maybe I’m bias.

How are we defining great? If it is best inside the ring, Armstrong with Robinson as a close second. If we are talking global impact and impact outside the ropes, then I go with Ali and Joe Louis and Jack Johnson as close second and third.
