Fantasy Football Defense Rankings: Week 15 Top Picks, Who To Start, Sit, Sleepers

We're on to the second round of the playoffs, but like last week some of the top defenses face some very difficult matchups this week, making choices that much harder for owners hoping to make the championship round. The Arizona Cardinals and St. Louis Rams, two of the better DSTs this season, are squads owners should be wary of this week. For one they'll meet each other on Thursday night, a short week that leaves little time for key defensive players to recover from injury.
