Well, the problem is, even if you're a cerebral pitcher you still have to run it up there with velo. If you don't have it, hitters will just tee off. Velo kills, at every level.
To me it's kinda like QB. You can get by in rec league by being an athlete. The higher you go, the more accuracy matters but you also have to be a great athlete first and foremost. People don't realize how fast even guys like Peyton and Eli were in high school.
This is why so much money is spent by parents on velocity coaching, we all know you have to have it. It's also why arms are tearing up, as they are going beyond the limits of nature.
