The Kansas City Chiefs needed a quarter to get going last week against Pittsburgh, but once they turned it on, there was no turning back. The day before in Buffalo, the Bills needed no such warmup before torching the New England Patriots. On Sunday, both teams will meet in a rematch of last season's AFC Championship, with a return to the conference title game on the line in the 2022 NFL playoffs. You can stream the game on Paramount+.

Kickoff from Arrowhead Stadium is set for 6:30 p.m. ET. Kansas City is favored by 1.5-points in the latest Bills vs. Chiefs odds in the latest odds from Caesars Sportsbook, and the over-under is 54. Sunday's showdown will be televised on CBS and streamed live on Paramount+ with their MUST-HAVE Premium plan. Plus, you can watch games on ANY device!

Before you make any Chiefs vs. Bills picks and predictions, you'll want to see what the SportsLine Projection Model is saying.

The model, which simulates every NFL game 10,000 times, is up over $7,500 for $100 players on top-rated NFL picks since its inception six-plus years ago. The model enters the divisional round of the 2021 NFL playoffs on an incredible 137-97 run on top-rated NFL picks that dates back to the 2017 season. Amazingly, it hasn't missed a top-rated pick since Week 14 of the regular season.

The model also ranked in the top 10 on NFLPickWatch four of the past five years on straight-up NFL picks and beat more than 94 percent of CBS Sports Football Pick'em players four times during that span. Anyone who has followed it is WAY UP!

Now, it has simulated Bills vs. Chiefs 10,000 times and the results are in. We can tell you that the model is leaning Under, and it also says one side of the spread cashes in more than 50 percent of simulations! You absolutely need to see it before locking in your own picks.
