StuffsSTF
STF stands for stuffs in football. Tackles that stop a ball carrier at or behind the line of scrimmage on a run, credited in halves when two players share one.
How STF is calculated
Counted, in half-credits. STFYDS is the yards those stops cost the offense.
Interior linemen and linebackers lead it; it rewards run defense that tackles and sacks leave out.
