After defeating the Cincinnati Bengals 25-17 on Sunday, the Kansas City Chiefs won the AFC West for the eighth time in a row and received an automatic postseason bid. Last weekend, a number of scenarios began to come to pass, but in the end, the Chiefs secured the AFC’s third seed. They are stuck there, neither rising nor falling farther. This presents an intriguing situation for Week 18, which is the last week of the regular season.Quarterback Patrick Mahomes was ruled out of the game by head coach Andy Reid early in the week. It’s the appropriate call to sit a guy such as him, with nothing at stake in what is, standings-wise, effectively a meaningless game.
