I agree with you that all of that stuff is a big factor, but the combination of the pitch clock and the expectation that starters with go 5-7 innings instead of 9 means that are not trying to save their arm during the game. They are throwing every pitch as hard as they can with as much spin as possible and not getting much rest between pitches. It isn't any one thing; it is the combination of all of them putting more stress on arms and throwing more, harder, more taxing pitches in a shorter period of time than ever before. No idea how they fix it at the big league level, but I think max pitch counts per outing and per week at lower levels need to be a part of it.
They have pitch count limits in league ball and select ball but lots of folks abuse them.
I've personally witnessed a team have a kid switch jerseys so he could claim to be a different kid and throw 200+ pitches in a weekend. Parents and coaches have to care enough to enforce it. I've seen way too many parents and coaches push a kid to throw way too many pitches even at a really young age.
As I said, my older son is a freshman in HS, his school has a sophomore team, JV, and varsity. The sophomore team is actually all freshmen but whatever. They've played 8 games plus 5 scrimmages so far (missed out on 3 games from a tournament being cancelled a couple weekends ago when we had that freeze). On only 2 occasions has a kid thrown more than 60 pitches in an outing and in both cases the kid hadn't pitched for almost a week prior and didn't/won't pitch again for probably a week afterwards.
Now, we might be unique because we have a lot of arms. In those 13 games/scrimmages we have thrown 12 different kids and not given up more than 4 runs in a 7-inning game.
I don't have the stats from the scrimmages because we didn't keep a book but nobody threw more than 2 innings in those scrimmages and my son in the 8 games (he missed 2 with the flu) has thrown 4.2 innings and has 8 Ks, 2 H (one was a bunt single), while giving up 0 runs, and 1 BB. He's thrown a total of 61 pitches in those 4.2 innings.
