Los Angeles has produced only 16.8 points per game (29th) and is 25th in total yards at 292.8 per contest. The Bolts are averaging just 1.47 points per offensive possession (31st) and are last in turnover rate at 3.9% of their offensive plays. 

The advanced metrics aren’t any better, as Los Angeles ranks among the NFL's worst teams in nearly every major efficiency category through five games.

  • 32nd in offensive EPA/play (-0.207)
  • 29th in offensive success rate (37.8%)
  • 32nd in passing EPA/dropback (-0.232)

The Chiefs are one of three unbeaten teams left entering Week 6. They come into the game off a bye, with Andy Reid’s team 23-5 with 12+ days of rest. Kansas City has used a balanced attack on offense this season, ranking first in rush yards per play (5.50) and fifth in pass yards per play (7.80). 

Offseason free-agent signee RB Kenneth Walker III leads the NFL in rush yards per game with 134.3, while Patrick Mahomes is fifth in passer rating (106.2). The Chiefs have only trailed in 17.1% of game time this season and are 4-0 for the sixth time in the last 10 seasons.
