That dude's reasoning ignores the obvious. I've said it for the past few years, Perfect Game is killing baseball for the upcoming generation. Kids are pitching primarily to a radar gun and spin rate starting at 11 and 12 years old, instead of simply worrying about balls, strikes, and getting batters out. It's just a numbers game of how many arm blowouts that ultimately causes as pitchers get into their late teens and twenties. It used to be that TJ surgery was dominated by MLB; now, youth baseball makes up the highest percentage of TJ surgeries by far. Obviously, a lot of that is due to the lopsided numbers, but nobody had heard of a kid even needing TJ surgery until a few years ago. Velo (both pitching and exit) is the only thing that matters now.
I have a kid on my middle school team who is throwing 85 at 14 years old. It is cool to watch, but his arm will be done in a few years. But hey he got some cool PG hats and in a bunch of social media posts. My hardest task is getting him to throw in the 70s so he can throw strikes and actually get some outs if kids aren't just chasing him. I have another kid who has already had 2 arm surgeries at 14 from travel ball, so he can't pitch any more at all. But he got those cool plastic trophies, and PG made a shitton of money.
