triple defense

The triple option is an American football play used to offer several ways to move the football forward on the field of play. The triple option is based on the option run, but uses three players who might run with the ball instead of the two used in a standard option run.
The triple option forces defenses to worry about multiple running options on a single play. For the offense, the decision of who is to carry the ball—which option to use—is made during the play by the quarterback (QB). The QB makes the decision whether to give the ball to the fullback (FB) or, based on his read of the defense, to keep the ball. If the QB does choose to keep the ball after the initial snap, he still retains the option of employing a third option; handing the ball off to the tailback. If, for example, the DE is blocking the FB or for any other reason it appears to him that his group of ball- carriers are otherwise limited, he will simply keep the ball himself instead of handing it off. If the DE runs straight upfield or directly at the QB, then the QB gives the ball to the FB. The triple option can be complemented by fixed running plays which look like the triple option when they start, but use traditional blocking, as well as play-action passing.
There are three basic forms of triple option: the wishbone triple option, the veer triple option, and the I formation triple option. These differ in terms of the personnel on the field and their positioning prior to the start of the play.
