Cardinals Lead Five Teams in 2026's Toughest NFL Schedules

Dan Parr ranks the five teams with the toughest 2026 NFL schedules by opponents' 2025 win percentage: Cardinals (.538), Rams (.516), Seahawks (.514), Chargers (.522) and Cowboys (.493). He notes the Bears had the league's toughest SOS entering 2026 (.550), but SOS isn’t a perfect predictor, and provides a team-by-team snapshot of each squad's 2025 record and the brutal early-to-late-season stretches and primetime tests awaiting them (Cardinals vs. 49ers/Eagles/Chiefs; Rams with seven primetime games; Seahawks' late-season gauntlet; Chargers' tough midseason run; Cowboys' Brazil trip and heavy slate).
