In fantasy football, D/ST stands for Defense and Special Teams. Instead of drafting individual defensive players like linebackers or cornerbacks, your lineup features an entire NFL team's defensive and kicking/punt return unit. When the real-life Baltimore Ravens defense takes the field, their collective performance dictates the fantasy points your team earns for that slot.
Understanding how this unit scores points requires looking past traditional offensive stats. While quarterbacks and running backs rack up yards and touchdowns, a D/ST unit relies on big defensive plays, turnovers, and keeping the opposing offense off the scoreboard.
How Standard D/ST Scoring Works
Most default fantasy leagues score defenses based on a threshold system. Your defense usually starts the game with a set number of points (such as 10) and loses points as the opposing team accumulates real-life points and total yards.
Positive points are added through distinct defensive and special teams plays: More journalism by Bloomberg highlights similar views on the subject.
- Sacks: Typically worth 1 point each.
- Interceptions and Fumble Recoveries: Usually worth 2 points each.
- Safeties: Valued at 2 points.
- Blocked Kicks or Punts: Generally worth 2 to 3 points.
- Defensive or Special Teams Touchdowns: Worth 6 points (interception returns, fumble returns, punt returns, or kickoff returns).
Points are subtracted when the opposing team crosses certain offensive thresholds. If an opponent scores more than 35 real-life points or gains over 450 total yards, your D/ST score will often drop into negative numbers. This creates a volatile position where a late garbage-time touchdown by an opposing team can completely ruin a defensive fantasy performance.
The Dynasty Scoring Mystery
In dynasty leagues, where you keep your roster from year to year, treating D/ST the same way you treat redraft leagues is a major mistake. Dynasty managers often wonder why elite defenses rarely command high rookie draft picks or massive trade value.
The core issue is year-to-year volatility. Defensive performance in the NFL fluctuates wildly due to injuries, coaching changes, free agency departures, and brutal strength-of-schedule swings. A dominant defense in one season can easily plummet to the bottom tier the next year. Because defensive units lack the long-term career stability and asset appreciation of young wide receivers or running backs, investing heavy capital into a dynasty defense is inefficient.
Furthermore, many competitive dynasty leagues remove standard D/ST entirely, replacing them with IDP (Individual Defensive Player) formats. IDP leagues shift the focus to tracking individual tackles, passes defended, and solo pressures for specific players, mirroring how offensive positions are managed.
Streaming vs. Setting and Forgetting
When managing your weekly lineup, two primary philosophies dictate how fantasy owners handle the position.
The first approach is streaming. Instead of drafting a top-tier defense early, managers grab a unit in one of the final rounds and drop them immediately after Week 1. They then scour the waiver wire every single week to pick up whichever defense is playing the worst offensive opponent (such as a turnover-prone rookie quarterback on the road). Streaming requires active roster management and a keen eye for weekly matchups.
The second approach is setting and forgetting. This means drafting a powerhouse unit—such as the San Francisco 49ers or Pittsburgh Steelers—in the later middle rounds and starting them every single week regardless of the opponent, only pivoting during their mandatory bye week. While elite units rarely maintain top status indefinitely, having a high-floor defense saves valuable waiver wire bids.
Common Mistakes to Avoid
Managing your defense slot effectively requires avoiding a few common traps that plague inexperienced fantasy players:
- Drafting a defense too early: Never draft a D/ST in the single-digit rounds. Even the highest-scoring defense in the league rarely outscores replacement-level waiver wire options by enough to justify sacrificing early running back or wide receiver depth.
- Hoarding multiple defenses: Unless you are blocking an opponent during your league's playoff weeks, holding two defenses on your bench wastes a valuable roster spot that could be used on a high-upside backup running back.
- Ignoring the Vegas totals: When deciding which defense to stream, always look at the implied game totals from sportsbooks. Defenses playing in games with the lowest over/under totals generally offer the highest floor for fantasy production.

Frequently Asked Questions
Do return yards count for standard D/ST?
In standard league settings, individual punt and kickoff return yards do not count toward your D/ST score. Your unit only receives fantasy points if those returns result in an actual touchdown. However, some custom leagues award fractional points for every return yard.
What happens if an offensive turnover leads to a defensive touchdown?
If your team's quarterback throws a pick-six, the opposing defense gets credit for the touchdown. Your own team's D/ST does not lose points for the score itself, though points may be deducted if the opposing offense crosses standard points-allowed thresholds later in the game.
Why do some dynasty leagues ban D/ST?
Many dynasty commissioners eliminate D/ST because team units fluctuate too drastically from year to year based on luck and scheduling. They prefer IDP formats to reward individual player skill rather than a collective team bucket.
Should I drop my defense during their bye week?
Yes. Unless you roster a generational defense that you refuse to part with, holding a defense through its bye week forces you to drop a useful skill-position player. It is almost always better to drop your defense, pick up a streaming option for that single week, and stream fresh units going forward.
