Earlier quoted context omitted.
I think most professional athletes are highly intelligent, but some never learned to apply it to anything other than sport. Watch Kobe or LeBron on the court. There is an incredible awareness of the shifting context of the game and the available moves. In the greatest athletes it is faster and more fluid than in most athletes. It's a constantly shifting analytical mode that leans heavily on training and instinct, but…
While I completely agree about awareness being a form of intelligence, professional athletes (for the most part) are really on a different plane when it comes to physical metrics. An average person will never be able to attain a 4.4 40 for instance.
Totally, true, but the number of people who are good at professional football is a very tiny subset of the people who can run a 4.4 40.
