Betting notes: Sean McVay’s opening week winning streak

After a 2021 season in which underdogs had their fourth straight profitable season (52.6%), the 2022 season begins with underdogs again being the story. Ten teams are listed as home underdogs, the most in a single Week 1 in the Super Bowl era.

Since the 1970 merger, home underdogs have covered 54.2% of the time, including 56.4% in the last 10 seasons. Divisional home underdogs have done even better, going 13-2-1 ATS in the past 10 seasons in Week 1, including 10-5-1 outright.

Last season, underdogs had their best opening week since 1999, going 12-4 ATS. They had a winning outright record (9-7), the first time that had happened since 1983.

One of the most notable underdogs is the Los Angeles Rams on Thursday night against the Buffalo Bills. It’s just the fifth time that the reigning Super Bowl champion has been a home underdog in Week 1. The previous four went 4-0 ATS. The Bills enter the season as Super Bowl favorites, making it just the second time in the past 40 seasons that the reigning champion will face the preseason favorite in Week 1 (2013: Baltimore Ravens vs Denver Broncos).
