Quarter – the period football games are divided into; in the NFL, this is 15 minutes

Quarterback – the offensive leader who in most cases receives the “Snap” from the “Center” then usually either throws a pass or gives the ball to a running back; the quarterback is also in charge of calling the play in the huddle and signaling for an audible

Quarterback Rating – a measure of the “Quarterback’s” effectiveness in passing including yards per attempt, completion percentage, interceptions and touchdown passes

Quarterback Sneak – the quarterback takes a snap and quickly moves forward; usually designed to throw defenses off guard in short yardage situations

Quick Count – when the “Quarterback” hurries the “Snap Count” in order to throw the defense off guard 

Quick Kick – a formation intended to surprise the defense with a punt by lining up in a formation that would normally indicate a running or passing play.
