If you're asking the quarterback to do too much, he becomes more important. If you play well as a team, he is less important. Knowing, understanding, and managing a team's strengths and weaknesses are the hallmarks of good coaching.I agree that a team needs to work in tandem, that goes without saying. However, the QB position is THE most important on the team simply for the fact that he touches the ball every play. If he is ineffective that plays a larger role than at other positions.
