Team Defense/Special Teams
1 point - Every sack
2 points - Every team takeaway (interception or fumble recovery)***
6 points - Every TD (via interception return, fumble return, punt or kickoff return, blocked FG return, missed FG return, blocked punt return)***
5 points - Every safety
12 points - Every shutout **
8 points - Allowing between 1- 6 points **
5 points - Allowing between 7 - 10 points **
*** A double-turnover is when the Offense turns the ball over to the opposing Defense, which subsequently turns the ball over back to the Offense. In this case, neither the Offense's ball recovery nor any subsequent TD scoring on that particular play are scored as Defensive/Special Team scoring for that team. Defensive team fantasy points for touchdowns, fumble recoveries and interceptions are ONLY scored when the defensive unit is on the field.
