Buying or selling 3-0 NFL teams: Which teams are Super Bowl contenders and which are pretenders?

Out of eight undefeated NFL squads entering Week 3, the Seahawks, Bengals, and Eagles dropped their opening games of the 2026 season, leaving the Bills, Chiefs, Raiders, Vikings, and 49ers as the remaining undefeated teams. Buffalo secured a victory over the Chargers despite turning the ball over five times, driven by Josh Allen, Greg Rousseau, and running back James Cook III, with a tough matchup against the Rams looming in Week 5.

Meanwhile, the Raiders have started 3-0 under head coach Klint Kubiak against opponents who currently hold a combined record of 1-8, facing an upcoming stretch that includes games against the Chiefs, Patriots, Bills, and Rams.
