On average, a boxer successfully moves up ONE major division (eventually to heavyweight) for every 3-4 years.
A) Are they really that great (if so, why did the ever lose, especially via KO/TKO?)
B) Did they benefit from complementary matchups (if singularly yes, why is this list not much longer?)
C) Is there something additional going on - aside from or in addition to greatness and fortunate circumstances?
If you think it is A or B or some combination of the two, this conversation is over.
If you think that it could (possibly) be C, then read on.
A massive amount of actual fight history - via private research - was given to advanced AI models available to the general public.
Then, in segments, the above list was then given to the AI.
After much discussion and debate, the AI agreed on the thesis and proceed to do bout simulations based upon fighters that were given (from boxing history, circa 1880s to 2020s).
The results - via PDF links - are in my book (in the Introduction section).
If you have 'Kindle Unlimited', you can access for free as part of you membership.
If not, Amazon is offering a free 30 day trial.
All of the data that the AI programming was based on is in the book (Introduction section, PDF links, first PDF is titled "Anything You Can Do, I Can Do Better").
Check out, if you are interested - and I hope you enjoy it!
