By far, Blitzing is the most complicated procedure in the game. Only players with giant claws for hands can do it. Each player who Blitzes the quarterback must first input a long series of commands. If they fail, the quarterback will almost always get the first down. Several middle linebacker Blitzes, such as Pummel, almost never fail, while the most complicated Blitz, Bum Passrush, Blitzes a safety and both corners, but will guarantee a sack if successfully executed.
