The two-time defending Super Bowl champion Chiefs are 11-1. They are at the highest elite level, several notches above the Chargers. Given three to 3 1/2 points for home field advantage, why then is Kansas City barely more than a field goal home favorite against Los Angeles? 

Why indeed? 

The Chargers beat the Falcons on the road inside a dome last week despite only gaining 187 yards facing a team with the fewest sacks in the league. No way will the Chargers be able to get away with that against the Chiefs on the road.

The warm-weather Chargers are looking at temperatures in the 30's with wind in the 10-15 miles per hour range for this Sunday night game in one of the toughest road venues in football. 

The Chargers are without their only decent running back, versatile J.K. Dobbins, and aren't likely to have their only decent receiver either with Ladd McConkey dealing with shoulder and knee injuries. Jim Harbaugh has turned Justin Herbert into more of a game manager than gunslinger and Herbert doesn't have the weapons to compete against Patrick Mahomes. 

Kansas City gives up the eighth-fewest points and yards per game. The Chiefs rank No. 3 in run defense. 

LA's strength is pass defense. The Chargers might have the best secondary in the league. However, the Chargers' run defense is merely average. They especially have trouble against opponents who employ a two tight end system like the Chiefs do. 

Kansas City should be able to run effectively against LA especially with Isiah Pacheco getting the rust off like he did last week. He and Kareem Hunt provide the Chiefs with a better than average 1-2 running punch. The Chiefs are back healthy at offensive tackle, too, with the return from injury of D.J. Humphries.
  
A strong ground game will allow Mahomes to pick his spots and lead to the Chiefs' seventh straight victory over the Chargers.
