Pro athletes are literally built differently. I went to high school with 2 successful MLB pitchers. Craziest story came from freshman year: During tryouts, one of the tests they had us do was to see how far we could throw a baseball. We walked out to the football practice field and lined up in the end zone. I threw 60-65 yards. Then a kid (the future pro) threw a ball out of the other end zone. As. A. Freshman. Every coach stopped what they were doing, handed him another ball and said “do it again”. And he did. By sophomore year he was throwing in the mid to upper 90’s. You cannot teach that kind of arm talent. You’re either born with it or you’re not. I was not.
