Statistical record 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.

Prior to "sack", the term "dump" was often used, as the NFL's statistical office recorded all sacks under "dumping the passer".
The NFL only began to keep track of times passers lost yardage in 1961 and no credit was given to the defensive player responsible until 1982.

In ball-playing competitive team sports, an interception or pick is a move by a player involving a pass of the ball—whether by foot or hand, depending on the rules of the sport—in which the ball is intended for a player of the same team ...
