The NFL season is over, which is good, because now we can start laughing at people who insist that Tom Brady is the greatest athlete of all time.
What Brady is, is the most accomplished modern player at the most important position in America's most popular sport. That's not the same thing as being the greatest athlete.
The Greatest Athlete of All Time is a category created to create debates, not end them, and that is fitting, because there is no rational way to compare men and women, those in individual sports and those who play for teams, and those who played in different eras.
