What counts as a sport

There are various debates around the world on what is a sport and what isn't. This argument is probably stronger in the U.S. than any other country. I believe that in order for something to count as a sport, than it must require a large amount of skill, physical ability, or a good combination of the two. For instance, C.C. Sabathia is largely overweight, but he is still arguably the best pitcher in baseball because of his solid combination of power and placement of his pitches. Offensive Linemen combine a small amount of skill with a large amount of physical ability, and Quarterbacks do just the opposite. My key point of this post is to underline that NASCAR isn't, and will never be, a sport. I understand that I've just alienated half of the country, but driving a car doesn't take nearly enough skill to compensate for the lack of physical activity that driving requires. If it was, then that 300 pound idiot who cut you off in traffic, then slowed down, would be considered an "athlete". So with this in mind, I say that NASCAR, F1, and the like, are all part of the entertainment part of ESPN , but not the sports
