Robin Renner, head baseball coach at Neuqua Valley High School, believes club teams and AAU can provide benefits but also come with risks for high school athletes. He allows his players to play on travel teams during the summer but structures their schedule to balance it with his high school summer team. Renner is concerned about overuse of young arms and encourages taking months off from baseball each year. He also thinks students should play multiple sports instead of specializing in one to prevent physical tolls on their bodies.
