I’m pretty sure every school threw their best pitcher multiple times per week. That’s what we did too. But most of the pitchers I played with also played another sport during the offseason so they weren’t throwing year round. Everyone was a big proponent of the “John Smoltz” philosophy. If you were stretched out enough you could easily pitch 3 times per week. I’m not that old but it was a different time, back when pitchers threw complete games and be ready to pitch the next game of a double header too if need be.
