Chiefs replace Bills as betting favorites to win Super Bowl LVII

The 9-2 Kansas City Chiefs are on track to enter December as the betting favorites to win Super Bowl LVII in February 2023. 

As David Purdum explained for ESPN, the Chiefs have leapfrogged the 8-3 Buffalo Bills in Super Bowl betting odds for the first time this season among sportsbooks. According to Oddschecker, multiple outlets listed the Chiefs as +400 favorites to hoist the Vince Lombardi Trophy early next year as of Monday evening. The Bills, widely perceived as preseason favorites to win Super Bowl LVII, were at +450 odds. 

The 10-1 Philadelphia Eagles were at +600. 

"The big reason for the Chiefs becoming Super Bowl favorites is the Josh Allen factor," Caesars Sportsbook assistant director of trading Adam Pullen told Purdum. "We just don't know if we'll see the same Josh Allen that we saw before the injury."

Allen reportedly suffered a worrisome injury to the elbow of his throwing arm during a loss at the New York Jets on Nov. 6, and that issue could bother him through the remainder of the season. The Bills have won two straight games coming off back-to-back defeats but only managed to beat the 4-7 Detroit Lions by three points (28-25) on Thanksgiving Day. 

Meanwhile, Kansas City lost to Buffalo 24-20 on Oct. 16 but has since notched five straight victories to move to the top of the overall AFC standings. The Chiefs next play at the 7-4 Cincinnati Bengals this coming Sunday, while the Bills are at the 6-5 New England Patriots on Thursday night. 

Pullen added during his comments that "question marks about Allen and the Bills offense" resulted in "a flip of the favorites" coming off the holiday weekend.
