I agree that they are incredible athletes, but I don't see why football's players are better athletes than those in other professional sports. The winnowing process is just as brutal in soccer/football, basketball, hockey, baseball, track, swimming, gymnastics (if you want some incredible athletes - wow), wrestling, boxing, etc. etc. Why is Tom Brady a better athlete than Floyd Mayweather? Than Lionel Messi?
