Some of the worst pitching coaches I've seen are well-meaning young women who pitched in college. I will agree that playing at a high level CAN give a former player some advantages as a coach that a non-player (like me) won't experience. But someone who has a passion for the game, a passion to improve knowledge, and especially a passion to help young women grow in the sport and in life... that person is likely going to be a fine coach.

Being a female ex-collegiate player is one of many attributes coaches can have. All other things being equal, I prefer the ex-collegiate female.
