John,
Like many other college coaches, I’m skeptical about different training products/devices. I recently worked a camp with a Michigan State and Coastal Carolina coach and asked them about their experiences with the Power Drive and both spoke highly of it. It’s one thing for a coach to believe in a drill, the key is for a player to believe in it and in both cases they said that their pitchers gave them positive feedback.
Please give me a call when you get a chance. Mornings are the best time to catch me as we practice in the afternoon.
Best wishes!
Ben
