what was Wladimir's best performance?

can you imagine what Cassius Clay would do with his slashing jab and bicycling about, then darting in with One-Two's to wlad's crystal chin? Then dancing outside, then around again. That's a 6 round fight with Wlad sucking wind and sliced up and quitting on his stool or the doctor says "Son, you'd have lost less blood if you went to fight against Putin."

I don't recall Ken Norton having a rough time with Ali and he was a bit chinny

I'm a bit surprised you would rate Ali post 1970's to the kid named Clay. (64-67)
