Los Angeles Chargers at Los Angeles Rams: Chargers’ Protection Problems Put a Touchdown Margin in Play

The personnel swing

Derwin James’ hamstring setback is a significant development for a Chargers defense that has been doing more than its share. James did not practice Wednesday, and Jim Harbaugh said the safety could be headed to injured reserve. Starting guard Kayode Awosika also sat out with a fibula injury.

That compounds a protection problem that has shaped the Chargers’ 0-6 start. Four rookies have been working along the offensive line, including Jake Slaughter at center after Tyler Biadasz’s season-ending knee injury. The Rams have not produced a huge sack total, but they just held Las Vegas to 48 rushing yards in a 35-21 win. Los Angeles should be able to control early downs and force Justin Herbert into obvious passing situations.

Ladd McConkey’s full participation and the Chargers’ bye are meaningful counters. A simplified offensive plan may help, but it cannot completely hide an inexperienced line against a defense ranked among the league’s better units by EPA.

The finishing gap

The Chargers’ defense is the strongest argument against laying points. It has defended third down and the red zone well enough to keep games from getting out of hand, and Khalil Mack can test a Rams front that listed center Coleman Shelton as a nonparticipant Wednesday.

Still, the broader drive profile favors the Rams. They rank first in total offense, while the Chargers are last in scoring and 28th in yardage. The Rams also enter with a top-10 offense and top-six defense by EPA, along with the league’s fourth-best offensive success rate.

The red-zone split matters most for the spread. The Rams are turning 69% of their trips into touchdowns, while their defense has allowed touchdowns on only 46%. The Chargers have reached the red zone just 2.5 times per game. Even if their defense makes Matthew Stafford work between the 20s, Los Angeles is much better positioned to turn its best drives into seven points rather than three.

Staying below seven

There is an under case at 45.5, but the Rams’ scoring ceiling makes the side cleaner. The moneyline is too expensive at -295, and laying a full seven gives away the most valuable half-point on the board.

My projection is Rams 27, Chargers 17. That accounts for some post-bye improvement from Herbert without assuming one week off repairs an offense averaging 15 points. The Rams’ advantage in protection, early-down consistency and red-zone execution should create enough separation.

The recommendation is Los Angeles Rams -6.5 at -110 with Fanatics.
