In Week 1, Justin Herbert faces the Kansas City Chiefs in São Paulo, Brazil, with a balanced offensive approach under new head coach Jim Harbaugh. The latest matchup intelligence highlights Herbert's past success against KC, averaging 232 passing yards over five games, including standout performances with 279 and 313 yards. Facing a Chiefs defense led by Steve Spagnuolo, known for its aggressive pass rush and 37% Cover 1 usage, Herbert must navigate a complex mix of man and zone coverages, with corners like Trent McDuffie. The Chargers' 54.1% pass rate and reliance on hitch curl routes may challenge Herbert against KC's 58.5% pass defense focus. Projected for 15.49 points (QB11), Herbert is a QB2 with moderate-confidence, given the defensive schemes and historical performance.
