Re: Mike Tyson's prime
The other big ignored factor is every fighter has a prime and optimal point in their career's. Usually between years 3-6 or 4-7. How do they do when their game is 10% less?
What has to be done to stay on top is to try and alter parts of the game to compensate for the subtractions. And some fighters just do not do this well and some do. But it certainly is possible to work and continue to evolve, but it is a skill or discipline that not all fighters or all champions have.
