There are two types of positions in football: an offensive and a defensive position.
What are the offensive positions in football?
Offensive positions are quarterback, offensive lineman, running back, fullback, and wide receiver.
One of the most essential offensive positions is the quarterback. The quarterback is the leader of the team. He gets the ball at the beginning of each play and makes the decision whether to throw the ball or run it.
The protectors of the quarterback are the offensive line. The offensive line’s job is to defend the quarterback or the running back, especially while they have the ball.
As an additional protection there are the running-the-ball positions of running back and fullback. These positions are located in the backfield, behind the quarterback.
The last offensive position is the wide receiver. This position has the main objective of receiving (catching) the ball when the quarterback throws (passes) it. He is usually tall and quick.
What are the defensive positions in football?
Defensive positions are defensive lineman, linebacker, cornerback, and safety. The defensive lineman are usually trying to immediately tackle the quarterback. Linebackers are the most important line-up of the defense. They are the quick, hard hitters. Cornerbacks are in charge of defending the wide receiver so he cannot catch the ball and run with it, while the safeties usually assist the cornerbacks and other defensive positions.
Where did they get the shape of the football?
The shape of the football comes from the shape of the ball in the game of rugby. A football has an elongated ball with pointed ends. The ball is perfectly designed for the player to hold it easily and has a nice aerodynamic motion when it is perfectly thrown. It also has an unpredictable bounce when it hits the ground.
The ball is eleven inches long and about nine inches wide. All of the manufacturers put some laces on one side so the players can grip and hold it easily.
