Super Bowl 2023: Chiefs could become second champ in row with losing ATS mark after 30-plus years without one

Chiefs #Chiefs

The Super Bowl LVII matchup is set, as the Kansas City Chiefs and Philadelphia Eagles will face off in Glendale, Arizona on Feb. 12. Patrick Mahomes and the Chiefs have played on this stage before, while the Eagles are back in the Big Game for the first time since the 2017 season thanks to Jalen Hurts and the ferocious Eagles defense.

At Caesars Sportsbook, the Eagles opened as 2-point favorites over the Chiefs after Philly became the fourth team in NFL history to win consecutive playoff games by 24-plus points. The other three teams all went on to win the Super Bowl. Entering the final week of the 2022 season, the Eagles hold a 10-9 ATS record on the year. 

As for the Chiefs, they are 1-1 ATS in the postseason. They covered in the AFC Championship matchup by defeating the Cincinnati Bengals by three points, but didn’t cover the number against the Jacksonville Jaguars in the divisional round. That gives Kansas City an 8-11 ATS record on the year. 

What’s fascinating is that if the Chiefs do win Super Bowl LVII, they will become just the second team in over three decades to have a losing record against the spread. The last team to do it? That actually happened last year, with Sean McVay and the Los Angeles Rams. 

Check out how every Super Bowl winner since 1991 has fared against the spread below. (Data comes from Team Rankings, Maddux Sports and SportsLine)

We don’t often see the Chiefs as underdogs, so it will be interesting to see how this line moves over the next two weeks. In fact, the Chiefs have been favorites in 15 straight playoff games, and Mahomes has never been a playoff underdog. It appeared for a moment that streak was going to be snapped in the AFC Championship game, but the Chiefs ended up closing as two-point favorites over the Bengals. If you were curious, Mahomes is 7-1-1 ATS and 6-3 SU in his career as an underdog.

Per SportsLine data scientist Stephen Oh, the initial simulations for Super Bowl LVII like the Chiefs ATS, and the Under. The sims project Kansas City to score around 23 points, but hold Philadelphia under 25 points.
