Note: If the defense gets a sack, that same team will get 2 points. If the defense gets an interception, the team will get 1 point. The defenses get no points for forced fumbles, fumbles recovered, blocked kicks, or tipped passes. You will know that the game has put up points on the board when a "boing" sound is heard after a sack or the interceptor is tackled.
