To be sure, when we are talking prime, are we talking about physical or fight prime? Because clearly they are both very different.

For example, since people have mentioned Hopkins, the 28 year old Hopkins that lost to RJJ was in his physical prime but the 36 year old Hopkins against Trinidad was the better fighter overall. Or take Pac as an example, the 25 year old one was physically in his prime but the 30 year old one is much better overall.

So which prime are we talking about? Fight prime or physical prime?

This is like the definition of elite, different meanings to different people.
