Tommy John's heart is in the right place, but this is a classic case of wanting to look backward when we need to be looking forward. We don't have any data about arm injuries from 1960 when Tommy was in high school. I'd bet anything that his high school PCs and rest periods were ridiculous by today's standards, yet he pitched 10 years in the Majors before needing the surgery. He had the right genetics, just like the guys with injury-free elbows today.
Everyone wants to throw hard. It's not solely about scholarships and the MLB Draft, it's about competing. We're in the early stages of understanding how to protect throwers' elbows and shoulders, but smart people are making progress. I'm confident that we'll be much better at arm care in 10 years because of research and development. We won't be any better off if we go back to the good old days.
