re: Anyone complaining about pitch count

Yes, all of those things influence arm injuries. One big factor is that a lot of kids don’t throw enough. They pitch a lot, but they don’t throw in between. So the only throws they’re making are high intensity without building strength. They show up at tournaments on the weekend and throw max effort, and that puts big strain on weak arms. Historically, pitch counts have been way higher than they are now, yet arm injuries are through the roof where they were fairly rare before.
