My point is that managing is about teaching and teaching is about being zone A on the fundamentals. There's not only the time for practice and the time for the games. There's as much if not more time in mental preperation. Seriously, it does require as much as one can give and the best that one can give. Managing successfully in any organization requires continous personal development.
Baseball is no different.
Reading includes both books on instruction and books about managers. Go to as many clinics as you can. Watch the drills, listen to the instructions and pay attention to how the players and instructors go about teaching. As you take in information about the game, incorporate what you've learned into your current instructional portfolio. Always be adding more knowledge, more techniques, and a deeper and fuller understanding of the game.
