NFL Week 4 2026: Who to Start and Who to Sit in Fantasy Football

As the 2026 NFL season enters Week 4, the picture surrounding both teams and players has become far clearer after three weeks of play. Surprises have come in quick succession, with both the Minnesota Vikings and Las Vegas Raiders opening the year at an impressive 3-0. On the other side, the Houston Texans and Los Angeles Chargers are already mired in crisis with 0-3 records through the first three weeks. For fantasy football managers, those opening weeks have provided a clearer view of who can be trusted and who has been a disappointment. Week 4 also brings a set of intriguing matchups, forcing fantasy managers to make several difficult decisions about their starting lineups. After three weeks, the data is finally thick enough to separate genuine signals from temporary luck. Some players have shown remarkable consistency, while several highly touted names have failed to deliver. Carefully analyzing the numbers, opponents, and tactical context will help managers make the most accurate decisions. The key is to look at long-term trends rather than relying on a handful of isolated games. Teams like the Vikings and Raiders are showing that stability on defense and efficiency on offense can make a major difference. Below is a detailed breakdown of who to start and who to sit this week, based on real data and specific matchup context. The most notable bright spot comes at the quarterback position in New Orleans. This player has scored at least 22 fantasy points in every game this season and leads the NFL in both pass attempts and completions. He has thrown for at least 250 yards in each game, producing multiple touchdowns along the way. That impressive run could easily continue in Week 4 against a weak Atlanta Falcons defense that has surrendered plenty of passing yards and touchdowns in recent weeks. With the New Orleans offense operating smoothly, another strong outing from this quarterback is entirely predictable. At running back, Tuten of the Jacksonville Jaguars is showing remarkable progress. His rushing success was on full display during the demolition of the New England Patriots in Week 3. A 90-yard rushing performance earned him 17 fantasy points and marked the third straight game in which he rushed for at least 65 yards. This New Jersey-born star has proven his quality and has a chance to shine once again against a Cincinnati Bengals defense that has looked vulnerable to the run. This is the ideal moment for Tuten to cement his place in many fantasy lineups. At wide receiver, Downs is developing into a reliable fantasy option. With five catches and 70 receiving yards in each of his last two games, he has scored 26.9 points over the past two weeks without finding the end zone. He is expected to see plenty of the ball against the Washington Commanders in London. Crucially, Washington has allowed more fantasy points to wide receivers than any other team in the league this year. This 25-year-old out of North Carolina is showing positive signs and deserves a starting spot in your lineup. Johnson is also a logical start, having posted double-digit fantasy points in every game this season. He has developed an impressive connection with quarterback Tyler Shough, and the pair look primed for a big outing against the Falcons. Atlanta's weaknesses against the pass have been clear all year, and Johnson is likely to see plenty of the ball. It would be a big surprise if he did not have a productive week. While Johnson is expected to deliver serious numbers on Monday Night Football, the same cannot be said for Pitts. On defense, the Minnesota Vikings are the top choice. Through three weeks, the Vikings' defense has recorded 14 sacks, more than any other team in the league. Their defensive strength makes it unlikely they will concede many points against a Miami Dolphins offense that has not managed more than 13 points this season. Miami quarterback Malik Willis already has four turnovers this season, and it would be no surprise to see the Vikings force more errors from him at US Bank Stadium. The Los Angeles Rams may be 1-2, but they have put up 54 points over their last two games, even without Puka Nacua. The star wide receiver is expected to return from injury in Week 4, meaning the Philadelphia Eagles will likely have their hands full on defense. While many experts focus on the players who are thriving, there is an overlooked reality: the struggles of some big stars stem from the system itself rather than individual form. Herbert of the Los Angeles Chargers is a prime example. Through three games, he has failed to reach 14 fantasy points in a single game, with three touchdowns against four interceptions and three fumbles. His difficulties are not merely a matter of form but reflect the instability of the entire offense. He badly needs a strong performance to restore his confidence, but he is unlikely to find it on the road against a Seattle Seahawks defense that has done a great job limiting opposition passing yards. Sitting Herbert until he shows signs of returning to his best is entirely reasonable. Similarly, Hampton of the Chargers is getting plenty of snaps and touches but is not doing enough with them. He has already posted two single-digit performances and may find it tough against the Seahawks on Sunday. Seattle has not allowed a running back to record 60 rushing yards in eight consecutive games, making Hampton a highly risky Week 4 start. Williams of the Detroit Lions is another intriguing case. He has all the tools to be a major threat, but the numbers in 2026 do not support him. The 25-year-old is averaging just 1.2 yards per route run, with a lowly 16% target rate. His natural ability always leaves the potential for big numbers, but against a Carolina Panthers defense that has given up few points to wide receivers this season, benching him may be the wise call. Pitts of the Atlanta Falcons is a regrettable story. He has just two catches for 20 yards through three games. The issue is not entirely his fault, as Pitts has only an 8% target share, meaning he barely gets any chances with the ball. New Orleans may have allowed 35 points in its home opener against the Raiders, but it is unlikely to make life easy for Pitts and the Falcons in the second of back-to-back home games. Finally, the Philadelphia Eagles defense is one to avoid. When you add Philadelphia's relatively low sack rate to its poor fantasy returns this season, sitting the Eagles' defense is the sensible move. Week 4 is not only a moment for teams to assert their standing but also an opportunity for fantasy managers to adjust their strategy based on real data. The right choices at this point can make a major difference over the rest of the season. The key is to distinguish between sustainable signals and temporary fluctuations, because in fantasy football, patience and data-driven analysis usually beat emotion. As teams like the Vikings and Raiders continue to surprise, the question is whether struggling sides like the Texans and Chargers can find themselves again. For fantasy players, closely monitoring developments and adjusting lineups in time will be the key to success this week and for the road ahead.
