Fantasy football managers facing roster decisions for Week 4 of the 2026 NFL season must sort through key injuries, backfield rotations, and favorable matchups across the league. Analysts and model projections offer different paths for streaming quarterbacks, buying low on slow-starting running backs, and targeting porous defenses.
Marcus Mariota and Jordan Love Shape Quarterback Strategy
Fantasy managers sorting through quarterback options outside the top tier face a choice between an established backup taking his show on the road and an inconsistent starter catching a struggling opponent. Marcus Mariota heads to London for the Washington Commanders following a strong outing where he helped engineer one of Week 3’s biggest surprises by tossing three touchdown passes in an upset over the Seattle Seahawks.

Mariota squares off against an Indianapolis Colts defense that is dead last in total defense, 30th against the pass, and 29th in points allowed. On the other side of the Atlantic, Josh Downs enters the London matchup as a primary target for fantasy managers after seeing a team-high 11 targets, sporting a 29% target share and seeing a target on 30% of his routes, facing a Washington Commanders secondary that has allowed the most fantasy points to receivers.
Meanwhile, Green Bay Packers quarterback Jordan Love looks to steady an offense against the winless Tampa Bay Buccaneers. Thomas Carelli of Sports Illustrated points to the venue as a recovery spot for the Packers, noting that Love has the advantage of being three days more rested than his opponent, while the Buccaneers will start undrafted rookie Jalon Daniels at quarterback.
Backfield Shakeups Create Running Back Opportunities
Following a stellar performance against the 49ers where the third overall pick recorded 109 scrimmage yards, a receiving touchdown, and 26 touches—translating to his highest snap share of the season at 64%—Jeremiyah Love enters Arizona looking to build on that momentum. Running back depth charts are shifting rapidly due to injuries, creating both immediate starts and calculated trade risks. He next faces a Giants defense that has given up the 10th-most fantasy points to running backs this season, including games where Javonte Williams posted 72 yards and two touchdowns, Kyren Williams recorded 97 yards and a touchdown, Blake Corum added 92 yards, and Tony Pollard tallied 96 yards.
Addressing other backfield situations, Aaron Jones will celebrate his 32nd birthday in December and now prepares to clash with a Miami squad that has surrendered the highest fantasy point totals to running backs, yielding top-five weekly finishes throughout each of the first three games. For the Dolphins, the backfield is in flux after De’Von Achane suffered a torn ACL. Ollie Gordon II may have volume, but a Week 4 matchup against the Vikings arrives while Miami operates behind a unit ranking 28th in adjusted line yards and holding the ball for the sixth-lowest cumulative time of possession at 28:49. Jaylen Wright offers change-of-pace utility as the fastest of the running backs, though questions remain regarding his vision and ability to get into space.
In London, Jacory Croskey-Merritt faces the Colts as Rachaad White deals with a shoulder injury that could keep him out, leaving recently signed Austin Ekeler and rookie Kaytron Allen as backups.
Defensive Units Target Vulnerable Matchups
Defensive streaming strategies point toward units facing turnover-prone offenses and depleted rosters. Brian Flores’ unit hosts a Miami Dolphins team tied for last in the league in scoring at 12 points per game and missing De’Von Achane.
In Las Vegas, Maxx Crosby and the 3-0 Raiders defense lead the AFC in fantasy points just one year after fielding one of the worst defenses in the league.
Other matchups highlight C.J. Stroud and the favored Texans projected to score 26 points in a game carrying a 48.5-point total against Dallas, which traded a second-round pick to the Steelers for cornerback Joey Porter Jr. Jameson Williams travels to face a Panthers team that placed exterior cornerbacks Jaycee Horn and Mike Jackson on Injured Reserve this week.
The Pittsburgh Steelers look to rebound on Thursday night in Cleveland against a Browns team that has been a favorable fantasy matchup for defenses by surrendering the fifth-most fantasy points per game to the position.
