Rules
To be considered a sack the quarterback must intend to throw a forward pass. If the play is designed for the quarterback to rush (run) the ball, any loss is subtracted from the quarterback's rushing total. (and the play is ruled a Tackle-for-loss as opposed to a sack) If the quarterback's intent is not obvious, statisticians use certain criteria, such as the offensive line blocking scheme, to decide. Unique situations where a loss reduces a quarterback's rushing total (not a sack) are "kneel downs" (used to run time off the game clock).
A player will receive credit for half of a sack when multiple players contribute to the sacking of a quarterback, even if more than two players contributed.

Famous quotes containing the word rules:
“Playing games with agreed upon rules helps children learn to live by rules, establish the delicate balance between competition and cooperation, between fair play and justice and exploitation and abuse of these for personal gain. It helps them learn to manage the warmth of winning and the hurt of losing; it helps them to believe that there will be another chance to win the next time.”
—James P. Comer (20th century)
“Under the rules of a society that cannot distinguish between profit and profiteering, between money defined as necessity and money defined as luxury, murder is occasionally obligatory and always permissible.”
—Lewis H. Lapham (b. 1935)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
