I don't think hitting a ball is athletics at all. More hand eye coordination. I would like to see Randy Johnson dribble a basketball while moving lol. Not to stereotype all baseball players, there are plenty of players that are world class athletes. I just think as a whole baseball requires less athleticism than other sports. It requires a lot less movemant than soccer, basketball etc...
The majority of the time while player are on the field they are just standing. The ball may come to them 3-4 times a game, the rest of the time just standing. The only real requirements that would call for athletic movemant would be running 20-30 feet to get a ball and making an accurate throw. Wich any fat a@$ could do. Plus you see more athletes making a transition from other sports to baseball. You will hardly ever see a baseball player try to make it in the NFL.
I have competed in every sport available in highschool. So I have an idea of the requirements of all of them.
