The NFL's landscape is shifting as only five teams remain undefeated after Week 3, following the losses of the Seahawks, Bengals, and Eagles. The Bills, Chiefs, Raiders, Vikings, and 49ers are now in the spotlight, with their potential for Super Bowl contention being analyzed.

Buying: Buffalo Bills

The Bills showcased resilience in their 24-10 victory over the Chargers, despite committing five turnovers. Key players include:

• Josh Allen: An early MVP candidate.
• Greg Rousseau: A leading contender for Defensive Player of the Year, achieving three straight games with two or more sacks.
• James Cook III: The league's top running back with an average of 6.0 yards per carry.

Concerns linger about their turnovers and defensive performance against elite offenses, which they will face in Week 5 against the Rams.

Selling: Las Vegas Raiders

The Raiders have started strong at 3-0, but their victories come against teams with a combined record of 1-8. Upcoming challenges include:

• Chiefs, Patriots, Bills, and Rams.

Their current statistics show a struggling rushing attack ranked 31st and a red zone defense ranked 27th. However, their start mirrors the 1992 Steelers, who found success later in the season.

Buying: Kansas City Chiefs

The Chiefs rebounded in their 24-10 win against the Dolphins, with Patrick Mahomes completing 83.3% of his passes. With five forced turnovers this season, they are in a strong position, currently holding the No. 1 seed in the AFC. Concerns about receiver depth and Kenneth Walker III's health persist but they remain formidable.

Selling: Minnesota Vikings

The Vikings have the potential for a playoff spot but lack a reliable quarterback, with their passing attack ranked 32nd. Kyler Murray's performance has been underwhelming, and their offensive struggles are evident, ranking low in multiple categories. Their defense, however, remains strong, allowing no rushing touchdowns so far.

Buying: San Francisco 49ers

The 49ers, led by Kyle Shanahan, rank high in both points scored and allowed. Brock Purdy is performing at an MVP level, and with stars like Christian McCaffrey and Deebo Samuel, they are well-equipped for a deep playoff run. Despite minor concerns about turnovers and the strength of their opponents, their track record under Shanahan suggests they are serious contenders.
