The gap between the No. 2 defense and the No. 12 defense in fantasy football this season is less than 2 points per game. There is no real every-week must-start lock. Savvy managers will be streaming defenses, or starting a new one every week, as needed based on whoever has the best matchup in a given week.
Consider that only two of the nine defenses that scored 10-plus fantasy points on Sunday were rostered in over 50% of ESPN leagues in Week 12.
