When was Ali Marciano I? I would like to think that I have a resasonable understand of boxing history and a bout between Ali and Marciano seems like one of the fights that even the casual boxing fan would know about.
Sadly your boxing knowledge doesn't seem to compare to your ability to read the thread you're posting in.
They had a bit of a sparring sesion and Marciano dropped the greatest. Ali developed quite a bit of afection for the old man after that.
Let's look at this another way. Ali was technically superior to Frazier on just about every level. He was taller, had a longer reach, had much faster hands, faster feet, better reflexes, a more economical style, arguably tougher...on nearly every level Ali trumped Joe. So why didn't he box circles around Frazier? Why didn't he make him look like a rank amateur? Why were their fights invariably life and death struggles? Because in most fights, it invariably comes down to will rather than skill that wins the day. The Ali - Frazier fights came down to will. They were a test of attrition. Sure, in a fight where one guy is head and shoulders above another in terms of skill, skill alone may win out, but in a case where athletes are in the same ballpark in terms of ability it's will, heart, commitment or whatever you want to call it that ultimately decides the outcome. I think a fight between Ali and Maciano comes down to will, and it would be a battle of attrition.
