I'm fortunate to have experienced a lot of different activities or sports if you will at some pretty intense levels. I don't criticize them simply because I appreciate how hard it is to excel at anything. My guess is that regardless of the sport, if you want to be among the best, not only do you have to have a little talent, you also have to be willing to do the work. None of us gets to decide what the criteria is - for me it was could I run a marathon in under 2:40. How many pull-ups or dips could I do before someone stopped me. How long could I keep moving up and down the court after the fat guys sat down. What is my resting pulse rate? I'm pretty sure that depending upon the criteria you choose to use, you could prove that there are a lot of professional athletes in s*** shape for sure. Some of them might not even be particularly "athletic".
