LOL too funny. MY dad always told be to throw fastballs because the curve balls would screw up my arm. So say that was late 70s where in th hell would he have heard that from ? he never played any sports really - foster kid Army at 16. just seems interesting as I always recall his comments as I was a pitcher/SS up until about 18 years old when I packed the baseball career in
The focus today is on spin rate and velocity which puts too much torque on the arm. Meaning they're doomed to have surgery in their early 30s if not sooner.
