THE OFFENSE!!!

The offense is important to winning a football game becasue without it you usually will
1. be disqualified and
2.if you weren't disqualified then you would still lose.

The offense is the part of a team which focus is on scoring points to win the football game.

There are 11 players on Offense. anymore players would become a foul.

The Offensive line is the group of players on the line of scrimmage who block to help move the ball forward. The Offensive line does not catch or run with the football.
The Offensive line consists of the Center, who conveniently is the "center" of the line and hikes the ball to the Quarterback when he sends a message to the center to hike the ball.
On each side of the center are the Guards. The Right guard and the Left guard. On the right side of the right guard is the Right Tackle, and on the left side of the left guard is the left Tackle.

On the end outside of a Tackle is the Tight End. In some formations, there could be two tight ends, though typically there is only one. The tight end can block or go out for a pass from the Quarterback.

In addition, on the line of scrimmage is typically a wide receiver. There must be 7 players on the line of scrimmage (the line where the football is from sideline to sideline) and 4 players in the backfield (behind the line of scrimmage).The Wide Receiver runs out to catch a pass or block downfield on running plays.
In a typical offense, there is also a Slot back, also called a slot receiver (shown on the image above as Z) who typically runs a pass pattern or blocks on runs.

The Quarterback is often the most well known player on a team. He is responsible for running the offense, calling the plays and changing them (by sending signals to his entier team), starting each play by sending messages to the center. The QB either hands the ball off, throws a pass, or keeps the ball and runs for yardage.

In the backfield, usually directly behind the QB are two runningback, the Fullback and the Tailback(also known as half-back). The fullback is the first of the two guys and the tailback is the second one back. In a typical play, the fullback may block for the tailback, though there are a lot of plays where the fullback can get the ball.
