Fantasy football managers setting lineups for Week 4 of the 2026 NFL season face a familiar dilemma: balancing elite defensive units against exploitable matchups. The Minnesota Vikings and Seattle Seahawks lead the weekly fantasy tiers, while streaming candidates like the Baltimore Ravens and Green Bay Packers emerge as popular options.
Minnesota Vikings and Seattle Seahawks Lead Week 4 Defensive Tiers
The Minnesota Vikings enter Week 4 as the top-ranked fantasy defense across multiple scoring formats. Through the first three weeks of the 2026 season, Minnesota leads the league in sacks with 14, alongside top marks in pressure rate, pass rush win rate, points allowed per drive, third-down defense rate, and red zone touchdown rate, according to RotoBaller data. The defense now faces a Miami Dolphins offense that will be without running back De’Von Achane for the remainder of the year due to a torn ACL, while the Miami unit has failed to exceed 13 points in a game this season.
Meanwhile, the Seattle Seahawks sit high in weekly defensive rankings despite stumbling against Marcus Mariota and the Washington Commanders in Week 3. Seattle ranks first in first downs allowed per game, second in third-down conversion rate, and third in both points per game and pressure rate. That pass rush sets up a favorable matchup against a Los Angeles Chargers offensive line missing starters and an offense that has struggled with protection and reads early in the season.
Streaming Options Highlighted by Ravens and Packers Matchups
Fantasy managers looking for streaming defenses on the waiver wire have several heavily favored units to target for Week 4. The Baltimore Ravens host the Tennessee Titans, an offense that ranks near the bottom in scoring and holds the league’s highest percentage of drives ending in punts at 59.3 percent. With Tennessee’s offensive line ranking 27th in pass block win rate, Baltimore is widely positioned as a top streaming play.

In Tampa Bay, the Green Bay Packers travel to face the Buccaneers. Green Bay draws an advantageous matchup against undrafted rookie free agent quarterback Jalon Daniels, who makes his first NFL start in place of the injured Baker Mayfield, who is sidelined with a thumb injury.
Chiefs, Steelers, and Other Notable Tier Two Contenders
Other units rounding out top-tier considerations include the Kansas City Chiefs, who rank inside the top ten in points per game and turnover rate heading into a matchup against the Las Vegas Raiders.
“One thing I mentioned to him was his guys play hard, and they play hard every snap. And that’s a positive that means they’re listening and trusting him. That’s a positive that he can build on, and he’ll do that. He’s a sharp guy, so he’s got a good staff, but they play hard.”

The Pittsburgh Steelers also remain a prominent Tier One option as they prepare for a divisional Thursday Night Football clash against the Cleveland Browns.
