wrong! a defense can indeed score, but in order to do so, they need to take the ball away. that means they either force an offensive player to drop the ball or they intercept a pass. teams with defenses that score at least once a game usually make it really deep into the playoff tournament at the end of the year. some teams live off of this. the chicago bears, for example, have a defense that routinely scores 2 or 3 times a game and once scored 5 times this year.
