NFL Week 3 betting: 5 biggest storylines, including sliding Chargers and surging Vikings

The first week of NFL Week 3 betting revealed several major storylines, with the Los Angeles Chargers facing a sharp decline in their fortunes and the Minnesota Vikings experiencing a surge in popularity. The Chargers were once considered a favorite against the Buffalo Bills, but that line has moved up to Bills -7, reflecting the betting market's loss of faith in the team.

The Chargers' struggles continued as they dropped to 0-2, while the Bills have been strong, going 2-0 in the first two weeks. The Vikings, meanwhile, have been impressive with a perfect 2-0 record and are now being viewed as a playoff contender. Quarterback Kyler Murray is expected to return from a concussion, and the Vikings are favored to win the NFC North at various sportsbooks.

In other news, the Dallas Cowboys are underdogs in their Week 2 home game against the Baltimore Ravens, with the Ravens at 3 points. Both teams are dealing with injury concerns, but the Ravens are favored to win in Brazil, with a total of 52.5 points. The Chicago Bears and Washington Commanders are both facing quarterback questions as key players go down with injuries.

The Bears saw Caleb Williams sidelined with a hamstring injury, while the Commanders lost Jayden Daniels to a dislocated elbow. The Commanders are currently 6.5- or 7-point underdogs at home to the Seahawks, while the Bears are 3.5-point underdogs against the Philadelphia Eagles. The Rams have also had their share of adversity this season, but their dominant Week 2 performance against the Giants has solidified their status as Super Bowl favorites.

For Week 3, the Rams are favored by 2.5 points in their tough road game against the Denver Broncos, despite historical strength in September due to the altitude factor.
