Explain the difference as you see it. I believe pitches are like plays. You hope the pitcher does what he is supposed to do with the ball like a football coach hopes the qb, rb, or wr does what he is supposed to do. You expect a result in football according to what you see from the defense and have scouted them to respond with no different than a batter in baseball. It is the same premise. Pitchers will not throw the ball where or how they should and football players will not do what they are supposed to do. But the knowledge and premise should be the same.
If all of these are true, if not let me know where I am missing something, then someone has to call the pitches and the plays. My premise is that a coach should know more than a HS kid, because very few college P5 catchers/pitchers call their own games. The coach should call the game or are you still saying the catcher is smarter than the coach?
