Bills vs. Chiefs showdown was one of NFL's most watched games in years

No, we can’t get enough of Patrick Mahomes vs. Josh Allen.

Just look at the numbers.

CBS drew a massive average audience of 31.2 million viewers for its national broadcast of the Kansas City Chiefs-Buffalo Bills showdown on Sunday – marking the most-watched NFL regular season game since 2007, excluding Thanksgiving and Christmas Eve games.

It ranks as the fourth most-watched game in a national broadcast window dating back to at least 1988, and it is among the 10 most-watched NFL regular season games in any window, excluding Thanksgiving matchups.

The audience is the biggest for a regular-season NFL game (holidays excluded) since a New England Patriots vs. Indianapolis Colts showdown – featuring Tom Brady and Peyton Manning – in Week 9 of the 2007 season.

Surely, the NFL and CBS hopes for a postseason rematch after the Bills’ 30-21 victory spoiled Kansas City’s perfect record. The outcome also put the Bills (9-2) in range to surpass the Chiefs (9-1) in the race for the No. 1 seed in the AFC playoffs.

The last time the teams met in the playoffs? CBS averaged more than 50 million viewers – more than any NFL game ever outside of a Super Bowl or conference title game — for the Kansas City victory in the AFC divisional round in January.
