While keeping a positive game script, the Bills out-physicaled the Chiefs and won the line of scrimmage. Running back James Cook went over 100 yards, and establishing that helped Bills quarterback Josh Allen gash the Chiefs defense on another of its weak points this season: play action.

Week 9 started with the Ravens trouncing the Dolphins 28-6 on Thursday night. Sunday's early slate was highlighted by a 31-point fourth quarter thriller between the Chicago Bears and Cincinnati Bengals, plus an upset by the Minnesota Vikings over the Detroit Lions.
