(CBS) Below, we look at Bills vs. Chiefs odds from BetMGM Sportsbook’s NFL odds before making our expert NFL picks and predictions later in the week.

The Bills survived a snowy, tightly contested game 27-25 Sunday against the Baltimore Ravens. QB Josh Allen didn’t have gaudy numbers, but he took care of the football and got it done. He was 16-for-22 for 127 yards, 0 TDs and 0 INTs. He ran 10 times for 20 yards and 2 TDs. The Bills defense turned the Ravens over 3 times.

The Chiefs took an intentional safety to run time off the clock near the end of the game, which cost them an ATS win as 9.5-point favorites, in a 23-14 win against the Houston Texans Saturday. QB Patrick Mahomes was 16-for-25 for 177 yards, 1 TD and 0 INTs. TE Travis Kelce had game highs with 7 grabs for 117 yards and 1 TD.
