Many teams have an unbalanced passing and running attack. For example, the Green Bay Packers clearly have a better passing attack than their running game. Let’s say that the opponents offense needs to stay off the field because the defense is tried. To do that, a team turns to the running game to control the clock. The Packers may have difficulties winning the game. The New York Jets fell behind to the New York Giants early and were forced to abandon the running game in effort to score points.
To win a football game, get ahead early and play your style of football and make the other teams offense change their style. The less a defense is on the field, the better.
