Chiefs vs. Ravens Week 3 Vegas spread, betting odds: Can Patrick Mahomes stay unbeaten career as underdog vs. spread?

There are almost too many story lines to delve into for the Monday night game to conclude Week 3 as the Kansas City Chiefs visit the Baltimore Ravens. It's a historic matchup between quarterbacks Patrick Mahomes and Lamar Jackson. Mahomes has never lost against the spread in the NFL as an underdog and is one here with Baltimore at -3 on the NFL odds. It's quite possible this is the last time in the regular season that Kansas City is a dog.

The Ravens are on a 14-game regular-season winning streak (covering the spread in 79 percent of those), while the Chiefs are on an 11-game winning streak including playoffs.

Mahomes is 5-0-1 ATS as an underdog. One can probably throw out when he was in Week 17 of the 2017 season in Denver as that was Mahomes' first NFL start and it was a meaningless one with the Chiefs locked into their playoff seeding and resting then-starting QB Alex Smith. The lone time Mahomes was a dog last year was in New England in Week 4, and Kansas City won 23-16.

The Chiefs have been on average 3.3-point underdogs in those six Mahomes underdog games and won them by an average score of 36.8-33.7.

Mahomes was of course the 2018 NFL MVP and opened the season as the betting favorite to win another. Jackson was the 2019 NFL MVP and the second-favorite to win No. 2. Both have been passed by Seattle's Russell Wilson, who was +320 entering Week 3. Wilson, Mahomes and Jackson seem likely to play musical chairs in that pole position all year. Maybe throw Aaron Rodgers in there too.

Monday will be the first time in NFL history that two former league MVPs under the age of 26 will face off. However, it's the fifth game in the last six years featuring the two most recent MVPs. The more recent winner has taken the past two: Mahomes on Dec. 8, 2019, over the Patriots' Tom Brady (2017 MVP), and the Falcons' Matt Ryan (2016 MVP) beating the Panthers' Cam Newton (2015 MVP) on New Year's Eve 2017. Jackson, meanwhile, is 4-0 SU and ATS as a starter in regular-season prime-time games.

Meanwhile, this will be the seventh time in NFL history that quarterbacks who won the regular-season MVP Award and Super Bowl MVP Award (Mahomes) in the same season will start against each other the following season. The Super Bowl MVPs are a fairly incredible 6-0.
