I think the pitch count aspect has evolved out of the LL abuse of arms--they instituted an inning count---then others went to pitch counts ---BUT -- a 30 pitch count in one inning is not the same as a 30 pitch count in two inning nor a 30 pitch count in three innings.
The pitch aspect for me has gone over the top with many coaches not knowing how to interpret it nor do pitchers parents undertsand it rspecially at the younger levels
WILL---perhaps we need to better educate the HS coaches and all the coaches at lower levels---for the most part the coahces at see at the HS travel team level are pretty good at not overusing pitchers---not to say it does not happen is an untruth but as a whole because it does.
The other thing is that HS coaches do not develop or carry enough pitchers on their rosters---here you could have a mandatory number where pitchers are designated and must be used.
