The Kansas City Chiefs' exciting overtime win over the Buffalo Bills made NFL history, as they will become the first team in NFL history to host four consecutive conference championship games. Before this stretch, the Chiefs had gone to just one AFC Championship game, but it's now become the standard for Andy Reid's club.

That's not the only history the Chiefs will make, as they also reached new heights in the world of gambling. According to ESPN Stats & Info, the Chiefs will be favored in their 13th consecutive playoff game this Sunday, barring injury or another outside factor that causes the line to move. It's the longest streak of being favored in the postseason in the Super Bowl era. The Chiefs are set to host the Cincinnati Bengals Sunday for the right to represent the AFC in Super Bowl LVI, and Kansas City is currently a 7-point favorite over at Caesars Sportsbook. 

Quarterback Patrick Mahomes is a big reason why the Chiefs are seen as one of the superior teams in the NFL, and he is 8-2 in playoff starts. While the Chiefs are used to being favorites, that doesn't always mean they will cover the spread. Kansas City is 10-9 ATS this season while Cincinnati is 12-7 ATS, and the Bengals upset the Chiefs in Cincy earlier this month, 34-31. 

If you're still wondering who to bet on this weekend, keep this stat in mind: In every single playoff game this postseason, the winning team has covered the spread.
