Defenses (DEF) to Start in Week 11 (2026): Best Fantasy Football Streaming Options

November 12, 2026

Frank Ammirante analyzes which defenses (DEF) to sit or start in Week 11 (2026) of the NFL season, and provides his best fantasy football streaming options.

Finding the right defense to stream can give you an advantage in fantasy football, especially when you target favorable matchups before your league mates.

As is always the case in this article, we're looking a week ahead, focusing on defenses rostered in fewer than 40% of Yahoo! leagues, giving you some potential options on the waiver wire.

With that in mind, let's take a look at why the Buffalo Bills, San Francisco 49ers, Dallas Cowboys, New York Jets, and Los Angeles Chargers are my favorite defensive streamers for Week 11.

Best D/ST Streaming Options For Week 11

Each of these D/ST streaming options is widely available. More popular options aren't listed here because they are currently rostered in more than 40% of Yahoo! leagues.

Buffalo Bills (35%) vs. Miami Dolphins

The Bills defense has been on a tear lately, scoring 14 and 15 fantasy points in its last two games. Buffalo has forced six turnovers during that stretch, giving fantasy managers exactly what they're looking for from a streaming defense.

Greg Rousseau has been a major part of that success, recording eight sacks this season. His ability to pressure opposing quarterbacks gives Buffalo plenty of upside, especially against struggling offenses that have trouble protecting the football.

Now, the Bills get an excellent matchup against the Dolphins, who will be without starting quarterback Malik Willis. Miami placed Willis on injured reserve with a groin injury, leaving second-year quarterback Kyle McCord to take over. McCord is set to make his first NFL start in Week 10, so he's a complete wild card. The likely outcome is that he deals with growing pains.

The Bills will be heavily favored at home against a Miami team that has struggled offensively throughout the season. Buffalo should have opportunities to play with a lead, forcing McCord into obvious passing situations. That would give Rousseau and the rest of the defensive line more chances to generate sacks and force turnovers.

San Francisco 49ers (31%) vs. Minnesota Vikings

Dallas Cowboys (15%) vs. Tennessee Titans

The Cowboys haven't been a productive fantasy defense this season, making them difficult to trust in most matchups. However, Dallas has forced at least one turnover in each of its last two games, giving fantasy managers a reason to consider the unit as a streaming option for Week 11.

The biggest appeal here is the matchup against Cam Ward and the Titans. Ward has been one of the NFL's worst starting quarterbacks this season, struggling with consistency and moving the offense downfield. These issues give opposing defenses opportunities to generate sacks and force mistakes.

Tennessee's offensive struggles could also work in Dallas' favor. If the Cowboys can establish an early lead, Ward may be forced into more obvious passing situations, creating additional opportunities for the pass rush to get home.

Dallas hasn't shown enough consistency to be considered a safe fantasy option, but this is the kind of favorable matchup where the Cowboys could reach double-digit fantasy points.

New York Jets (8%) at Los Angeles Chargers

The Jets defense has really struggled this season, making it difficult to trust in fantasy. However, New York has shown flashes of potential, especially with rookie edge-rusher David Bailey.

Bailey has been one of the few bright spots on this defense, recording 7.5 sacks and five forced fumbles through eight games. He was especially disruptive against the Chiefs, finishing with two sacks, two forced fumbles, and three quarterback hits. His ability to create turnovers gives the Jets some upside despite their defensive struggles.

David Bailey now has 7.5 sacks and 5 forced fumbles through his first eight NFL games.

Now, New York gets a favorable matchup against a Chargers offense that has been a disaster this season. Los Angeles has struggled to protect Justin Herbert, who has been under constant pressure and has made too many mistakes. That allows Bailey to continue his impressive rookie campaign.

The Jets are obviously a risky streaming option, especially considering how many points they've allowed this season. However, the Chargers' offensive struggles make this an appealing matchup to target.

Los Angeles Chargers (7%) vs. New York Jets

The Chargers defense has actually been better than their offense this season, although that hasn't translated into much fantasy production. Los Angeles is averaging just 4.0 fantasy points per game and has struggled to generate consistent pressure, recording only 13 sacks through eight games.

However, the Chargers could be worth considering as a desperation streaming option against Geno Smith and the Jets. New York is coming off a 35-12 loss to the Chiefs, with Smith throwing for just 165 yards while taking five sacks. The Jets have struggled to sustain drives, giving opposing defenses opportunities to capitalize.

Smith has generally protected the football this season, throwing only three interceptions through nine games. However, he's shown a tendency to make mistakes under pressure throughout his career, so the Chargers will have a chance to capitalize on those mistakes.

There's plenty of risk here, especially with Los Angeles still searching for its first victory. With that said, this is strictly a desperation play in deeper leagues.

Ranking the Week 11 Streaming D/STs

I'd rank these deep streamer D/STs in this article as follows:

1. Buffalo Bills vs. Miami Dolphins
2. San Francisco 49ers vs. Minnesota Vikings
3. New York Jets at Los Angeles Chargers
4. Dallas Cowboys vs. Tennessee Titans
5. Los Angeles Chargers vs. New York Jets

If you're in a league where more widely rostered D/STs are available, I'd consider the following matchups as well:

• Houston Texans vs. Indianapolis Colts
• Pittsburgh Steelers at Philadelphia Eagles
• Kansas City Chiefs vs. Arizona Cardinals
• Denver Broncos vs. Las Vegas Raiders
• Detroit Lions vs. Tampa Bay Buccaneers

Most of these defenses are rostered, but double-check your waiver wire to make sure. You'd be surprised; sometimes a fantasy manager may have dropped them if they had a bye or if they got off to a slow start to the season.
