Monday night will be the biggest divisional game for the Chiefs in a long time.

This season has been bumpier than expected for Kansas City, but there is still plenty to be optimistic about. The Chiefs will play in Mexico City with all five starting offensive linemen for the first time since Week 2, and quarterback Patrick Mahomes is healthy again. The Chiefs defense, though still with issues, is an improved unit from 2018.

The 4-6 Los Angeles Chargers are fighting for their playoff lives. They have talent across the board, but injuries have ravaged their season like so many times before. Quarterback Philip Rivers also appears to be on his last legs and it is becoming more difficult for him to shoulder the load.

Here are the keys to a Chiefs victory before they head into their bye week:

Improve red zone efficiency

The Chiefs’ offense is still an elite unit (No. 3 in the NFL), but the one area it is struggling in is scoring touchdowns in the red zone. Last season, the Chiefs scored red zone TDs 73 percent of the time, second-best in the NFL. This season they rank 26th, scoring TDs on just 47 percent of their trips to the red zone.

The Chiefs are settling for too many field goals, which is keeping their opponents in the game. With six games still to go, kicker Harrison Butker has already matched his number of field goal attempts from last season.

With Mahomes at QB and one of the best skill position groups in the NFL, there’s no reason for K.C. to be struggling to score TDs. The offensive line returning to full health might help.
