I came across this article.
50% of the top 10 were from the '80s (one just in the early '90s but 70% from 80s and 90s). I always told my son we seemed to hit more home runs in the 80s in High School than what the kids today seem to hit. We debate it... It has to be due to improvements in pitchers because the hitters have much better bats than in the 80s, are probably more skilled due to all-year coaching, and I would think they lift more. Thoughts?
