I tried to throw as hard as I could and I threw curve balls 'til my arm hurt. Kids will be kids. I will say that kids today probably get better "coaching" nowadays as to what I got in my day.
It really doesn't matter. The science is just so much "advanced" today. 6 man rotations will appear soon for all clubs. Starters will go once a week...and still not make it through 6 innings.
