So then you discount quite a bit of overall sports history? I understand the issue with exposure, but the truth of beating the best in front of you who know and practice the game is real. It was a smaller pool of occupants, but those who were best shine through. I'm sure you could theorize some person from another country could have done better, that's fine.. I'm dealing with reality.
Again, if you stuck MJ or Lebron back into 1962, and took away all of their time priviledges like back to the future such as their cross-training, early youth training, and intellectual strategies that were developed over time.. you'd have similar clunky, athletic oafs who existed in the 1960's.
You don't seem capable of comprehending the era-discrimination that you're violently giving off. You're avoiding my examples.
