KC falls to 0-2 after a 20-17 home loss to Philadelphia in Arrowhead’s high-profile rematch. Mahomes threw for 187 yards with a TD and INT, added 66 rushing yards and a rushing score. A fourth-quarter tipped pass through Travis Kelce’s hands swung momentum. Reid accepted full responsibility for coaching missteps. Week 3 features a primetime trip to MetLife to face the New York Giants, a critical bounce-back moment for KC.
