I do have their hypothetical Dream Match on DVD, shown at the theaters in January 1970, following the tragic death of Rocky Marciano. This was during Muhammad Ali's banishment from boxing. This will always forever be brought up in discussions like Ali at his peak vs another heavyweight champion of 1988, the 1963 version of Henry Cooper will always be brought up as if no other fighters ever hit the canvas before, except George Chuvalo, it never ends. Only arguments erupt, no gainful debates.
That man in your video -- whoever he is -- is one of those nostalgic Fleischer clones, pining for the days when tiny Italian heavyweights ruled the division. These kinds of pseudo-historians are a dime a dozen on boxing forums. You really should post a video of an actual boxer evaluating Marciano. This is just embarrassing.
Who's this "Ali" guy? Does he even have a YouTube channel? I was talking about the Boomer nostalgist in the video. He's probably Italian-American or something; that would explain the high opinion of Marciano.
