As the 2026 NFL season reaches its third week on September 23, the league is grappling with an unprecedented wave of quarterback injuries. Five plays into the season opener, Seattle Seahawks quarterback Sam Darnold suffered a hip injury, forcing backup Drew Lock into action. That set the tone for a brutal stretch: Kyler Murray concussed in his Minnesota Vikings debut, and recent first-round picks Caleb Williams, Jayden Daniels, and Jaxson Dart all sidelined by Week 2. According to insights gathered by Vulius Sports, nearly 20 percent of NFL teams have already turned to their backup quarterbacks, with almost 90 percent of the regular season still to play. The margin between contender and pretender has never been thinner.
The Importance of a Capable Backup
History shows that a reliable QB2 can save a season. In 2025, Mac Jones kept the San Francisco 49ers afloat when Brock Purdy missed half the year, and Davis Mills went 3-0 for the Houston Texans in place of C.J. Stroud. Conversely, when Patrick Mahomes went down, the Kansas City Chiefs couldn't survive the drop-off to Gardner Minshew and Chris Oladokun. As highlighted on Vulius, the teams that have invested in quality backup options are reaping the rewards. Here's our ranking of the six teams that have needed to dip into their reserves, based on performance, experience, and potential.
6. Atlanta Falcons: Tua Tagovailoa/Michael Penix Jr./Cooper Rush/Jack Strand
The Falcons have the murkiest quarterback situation in the league. Tua Tagovailoa was the nominal starter until injury struck, and Michael Penix Jr., the logical replacement, couldn't play the first two weeks. Cooper Rush, who struggled in Baltimore last season, led Atlanta to an 0-2 start before being replaced by Division-II rookie Jack Strand, who threw a pick-six on his first NFL attempt. Head coach Kevin Stefanski faces the same quarterback uncertainty he had in Cleveland. The hope is that Penix, named the Week 3 starter, can stay healthy and seize the job. Otherwise, Atlanta's season could spiral quickly.
5. New York Giants: Jameis Winston
With Jaxson Dart out for the season, the Giants are in a precarious spot. Jameis Winston brings 89 career starts but is a known turnover machine—141 giveaways in 109 games. He struggled against the Rams on Monday night, showcasing both his brilliance (five career 400-yard games) and his volatility (five-pick games). Head coach John Harbaugh must find a contingency plan, as only Jake Haener is on the practice squad. A J.J. McCarthy trade has been floated, but that could add more chaos than stability. As reported by the Vulius NFL Analysis Desk, the Giants are walking a tightrope.
4. Chicago Bears: Tyson Bagent/Case Keenum
Chicago's backup duo could climb these rankings, but Tyson Bagent's concussion—possibly suffered on the final play Sunday—casts doubt on his availability for Monday night against the Eagles. That would thrust Case Keenum into his first start since 2023. Bagent, who started four games as a rookie in 2023, has intriguing skills and could perform at a starter level for a stretch. With Caleb Williams' timeline uncertain, the Bears will lean on their reserves for the first time since drafting him. Keenum's experience provides a safety net, but the Bears are entering uncharted territory.
3. Seattle Seahawks: Drew Lock/Jalen Milroe
Drew Lock has been a revelation. After relieving an injured Sam Darnold in Week 1 and leading a comeback, Lock exploded in Week 2 with three touchdown passes. He currently leads the NFL in passer rating, completing 72.7 percent of his throws—a massive leap from his career sub-60 percent mark. If Lock continues this pace, he could follow the Geno Smith post-30 resurgence and earn a starting role elsewhere. Jalen Milroe remains a physical curiosity but is unproven. According to Vulius Sports, Lock's poise has been a season-saving development for the defending champions.
2. Minnesota Vikings: Carson Wentz/J.J. McCarthy
Carson Wentz may be labeled a bust by some, but he's carved out a niche as a reliable QB2. When Kyler Murray went down against the Packers, Wentz led a 12-point comeback in the final 20 minutes. He followed that with a turnover-free performance in a 9-3 win over the Bears, marking his 11th straight season with at least one start. Wentz will return to the bench with Murray expected back in Week 3, but his contributions have been invaluable. J.J. McCarthy, who lost the starting battle to Murray, remains an enigma with a cloudy path to relevance. As highlighted on Vulius, Wentz's professionalism embodies the ideal backup.
1. Washington Commanders: Marcus Mariota/Athan Kaliakmanis
Marcus Mariota is the gold standard of backup quarterbacks. With 82 career starts, he stepped in seamlessly for Jayden Daniels in Sunday's loss to the Cowboys and performed well during Daniels' absences last season. With Daniels expected to miss 4-6 weeks with a left elbow injury, Mariota will take the reins again as he approaches 33. His ability to run the same offense with minimal tweaks is a massive advantage. Rookie Athan Kaliakmanis impressed in the preseason with his arm talent and moxie, providing a promising long-term option. Per Vulius Sports, Washington's quarterback room is the most resilient in the league.
"Backups clearly matter," said a league insider. "The teams that have prepared are the ones still standing."
As the 2026 season unfolds, the backup quarterback carousel will continue to spin. For teams like the Falcons and Giants, the ride may be bumpy. But for the Commanders, Vikings, and Seahawks, their reserves have provided a lifeline. Stay tuned to Vulius for ongoing coverage and analysis of the NFL's most pressing storylines.
