The real issue in this fight was that they sucked; there was zero in the way of boxing skill. Yeah, I know short notice...That doesn't matter if you know how to fight and are a professional. What does it take to prepare for an opponent? THE FIRST ROUND, for a true pro; these guys were and are glorified amateurs.
To be so tired after a couple rounds, like Lewis? A PRO can get in and do 10 because he is a boxing professional. Vitali was eating those flush uppercuts again and again- a 'pro' would turn his shoulder and quit leaning in- and a few more would have finished him.
The night of the fight, I turned to my friend (he had sparred with Emile Griffith and spent considerable time around Liston) and said "Joe Louis is turning in his grave." It was a shameful night; like Arcel said, get two guys that cannot box and it'll be one hell of a fight.
