In football, a quarterback can run the ball. Running the ball entails pushing the ball down the field in order to gain a down or perhaps score a touchdown. The quarterback, like any other player on the field, may run the football. However, they will usually stay within the pocket or be pulled outside it.
The term "run the ball" means that the quarterback will take off running with the ball and try to get positive yards after contact. Often times this is done to avoid negative plays (such as sacks) or prevent the defense from getting off the field on third down. Quarterbacks who can run the ball often have more success than those who do not because they can use their mobility to set up play-action passes or keep the offense on the field when things go wrong.
Some examples of runners who used to run the ball but now primarily pass are Vinny Testaverde and Rick Mirer. These were two very successful quarterbacks in their own right - Testaverde won two Super Bowls with the New York Jets and Mirer was a three-time Pro Bowler with the San Francisco 49ers - but they was never able to lead their teams to the playoffs as runners because they did not have the arm talent needed to succeed as passers.
Quarterbacks such as Tom Brady and Aaron Rodgers are known for their ability to run the ball.
Running backs are also receivers, and they frequently catch many passes throughout a football game. The quarterback receives the ball from the center and runs the play. The quarterback can run with the ball, hand it off to a running back, or throw it to a receiver. Running backs often have more opportunities than other players because they always seem to be in the right place at the right time.
Most running plays start with a call of "Run!" which is passed along by word of mouth through the entire offensive line. If the line does not get the message across, then coaches will use other signals to let the runners know what is going on. For example, if there is a screen play called, the guards and centers would shout "Screen!" While this is happening, the quarterback reads the defense and makes his decision based on where he thinks the danger is most likely to come from. If he believes that there is no danger of being hit as he hands off the ball, then he will tell the guard to "Go!" At the end of the play, the guards would then shout "Right!" if they think that the runner is heading left or "Left!" if they think he's going right. These are just examples; there are many different calls and signs used by coaches to tell their players what to do next.
A running play happens when the quarterback delivers the ball to another player, who then attempts to carry the ball past the line of scrimmage and gain yards, or when the quarterback maintains the ball and goes beyond the line of scrimmage himself. The term "running play" can be misleading because many times a player will use other means to gain yardage (such as a sweep or a dive). However, if the player does not stop short of the end zone, then the play is considered a run.
Here are some examples of running plays: QB sneak - A quarterback can gain up to 10 yards by sneaking into the end zone. This play can also be called a fair catch because the ball is placed in the end zone by a player with possession. Triple option - Three players from one team will rush the ball carrier while the fourth looks for an opening. If there is no one behind him, he can take off for a big gain. Power O - Four offensive linemen versus four defensive linemen. They all try to push their guy out of the way so that nobody gets between the ball-carrier and the end zone. Wide receiver reverse - One wide receiver starts at the back left corner of the field and runs forward. The others stay put. When he gets to the middle of the field, he flips the ball back to the quarterback, who is now facing backwards.
