Chiefs, 49ers, Vikings Remain NFL’s Only Unbeaten Teams

After Week 4, the Chiefs, 49ers and Vikings were the NFL’s only unbeaten teams, with Kansas City surviving a 30-27 divisional battle against the Raiders. The Jaguars were emerging as a potential AFC contender, while talkSPORT’s rankings said an undefeated London stretch could put them in position to challenge the Chiefs for the top spot. New England’s Drake Maye rebounded with three touchdown passes to lead a 26-21 upset of the Bills, but the Chargers fell to 0-4 as Justin Herbert committed three turnovers in a loss to Seattle. The Rams also made a statement with a comeback win in Philadelphia, though analysts cautioned that even strong teams have weaknesses and injuries to star players could reshape the season.
