Key Points:

• Week 1 of the 2026 NFL season was marked by several dramatic games, including a thrilling overtime win by the Detroit Lions over the New Orleans Saints, a dominant 59-point performance by the Chicago Bears, and two rare scorigamis occurring in one day for the first time in seven years.
• Notable game grades include the Bills' 36-31 victory over the Texans, highlighted by Josh Allen's strong performance, and the Cardinals' 26-14 upset over the Chargers, where Arizona dominated in all phases, while the Chargers struggled offensively under new coordinator Mike McDaniel.
• Key losers from Week 1 include Browns QB Deshaun Watson, who struggled with turnovers and sacks, the Tennessee Titans under new coach Robert Saleh, and the Lions' defense that faltered in the second half against the Saints.
• Standout stats from Week 1 feature the Bears and Panthers combining for the highest scoring Week 1 game ever with 96 points, the Bears scoring six rushing touchdowns—the most in a Week 1 game since 1922—and Jets and Giants both winning their openers for the first time since 2009.
• Monday Night Football features a critical AFC West matchup between the Broncos and Chiefs, with experts largely favoring the Broncos to upset the Chiefs, who are relying on Patrick Mahomes returning from ACL surgery and a rookie left tackle; injury updates include Rams' Myles Garrett and Patriots' A.J. Brown both placed on injured reserve.
