The game of baseball cannot begin without the action of one position.

In basketball there is a lot of focus on the point guard. In football there is a lot of focus on the quarterback.

These are important positions, but there is no position that is more important than a pitcher in baseball.

There is so much responsibility that involves a pitcher. From throwing different pitches, knowing the various hitters, fielding their position, pickoff moves, to controlling the running game, to dealing with adversity, mental focus, and dealing with fatigue, a pitcher has a lot to deal with.

If one of these important parts of pitching is missing, you do not have a complete pitcher. Missing one of these components negatively affects all of the other components.
