INTERFERENCE: There is offensive interference, when blockers run in front of a running back, and defensive interference (or defensive pass interference), when a pass defender interferes with a receiver trying to catch the ball while the defender could not catch the ball himself (intercept). For example, a defender with his back to the ball who sees the receiver he's covering readying to catch the ball and then waves his arms in front of the receiver to distract him is interfering with the pass.

There are two basic types of plays: running plays, where the offense tries to run with the ball toward the opposition's goal line, and passing plays, where the object is to pass the ball forward towards the opposing goal line. A play can have minor variations each time, but will usually fit into some general categories. For instance, in a sweep, the guards pull from their positions to block for the ball carrier as he moves left or right, then up the field. In a draw play, the quarterback takes the ball from the center and moves back rapidly, acting as though he's going to throw it. When the defensive linemen get close, the quarterback then hands off the ball to a running back who hopes to quickly dart past the defensive linemen, who are still being "drawn off" by the quarterback. In an Action Pass, the opposite occurs, and the quarterback pretends to hand-off to another player only to retain the ball.
