Rams, Packers, Chargers, Patriots: Which Week 1 losses should scare us most?

Week 1 delivered several unexpected setbacks for projected powerhouses heading into the 2026 campaign. The Los Angeles Rams stumbled in a 20-point blowout against the San Francisco 49ers, while the Green Bay Packers collapsed by 17 points versus Minnesota after initially controlling the contest.

Elsewhere, the Los Angeles Chargers dropped a home tilt to Arizona by 12 points despite entering as heavy favorites, and the New England Patriots succumbed 13-10 to the Seattle Seahawks as Drake Maye threw three interceptions.

Historical trends dating from 2015 to 2025 demonstrate that an opening-week defeat is far from fatal for championship hopefuls. 9 percent of the time.

Rather than final scores or noisy metrics like turnover differential and yards per play, underlying markers like sack percentage allowed, third-down efficiency on both sides of the ball, and success-rate differential served as the real indicators, with teams finishing below the historical median in success rate qualifying for the playoffs only 30 percent of the time.
