Thats why they are hisorians, of course they will care more about the rise. Lady Gaga isn't just famous because of music critics, its the masses; same with Tyson. The casual fan loved Tyson going up, but his charades in and out of the ring made him memorable to those who don't care about boxing; same with Ali.
What is deranged is to believe the world of boxing fans is larger than the world at large. It may be an easy thing to prove how much in the mainstream news Tyson was during his rise, and how often he was in the MSM news for his loss to DOuglas, the ****, the earbite, and all the other craziness in his downfall.
Someone here who comprehends that the # of people on the planet is far larger than the # of boxing fans. There is even the famous line from the Pacino/Crowe movie The Insider. Said by the Mike Wallace character IIRC: "Fame lasts for 15 minutes, infamy lasts a lot longer." Though he may have said "a little longer", sarcastically.
At work, people who know nothing about boxing, talk about him knocking people out. I see some folks from time to time watch Mike Tyson best knockout videos on Youtube. So I am gonna say rise.
His rise, is what will forever be rememberd, their was a phrase around about the saverese fight which summed him up pretty well towards his fall, that he was 'loved by few,hated by many, but respected by all!'
Tough question. If it wasnt for his rise, his fall would have not had the same impact that it did. Therefore i have to go with his rise.
The Q is: which is more famous. Which I think can only mean which aspect is known to more people in the world at large. The rise or the fall? I doubt too many in the "real world" know who Berbick was or Michael SPinks. But I bet more people will know the things involved in his fall: loss to Douglas in Tokyo **** of Desiree Washington biting Holyfield's ear And again logically and chronologically because he was already famous when he "fell', the fall is far more well known. Many unknown people fall or **** up. Because they were not famous when that happened, no one knows. "Infamy lasts a lot longer than fame."
