The Los Angeles Rams and Chargers will face off Thursday night at SoFi Stadium in their final preseason game, with numerous roster spots and crucial backup quarterback positions still undecided.

Despite the limited stakes typically associated with preseason finales, both teams have significant evaluations to conduct. The Rams, considered Super Bowl contenders, will use the game to finalize their 53-man roster, particularly focusing on positions like backup quarterback, cornerback, offensive line, and defensive line.

Backup Quarterback Competition

The Rams' most prominent storyline revolves around the backup quarterback job behind Matthew Stafford. Stetson Bennett IV and rookie Ty Simpson are vying for the role, with Thursday serving as their final opportunity to impress. Bennett has held the advantage in practice, but Simpson has shown flashes of talent. Coach Sean McVay also needs to evaluate undrafted rookie Matthew Caldwell.

Meanwhile, the Chargers are also evaluating their backup quarterback situation between Trey Lance and DJ Uiagalelei. Both have had mixed performances throughout the preseason, and this game is critical for them to separate themselves.

Roster Battles and Defensive Line Decisions

For the Rams, many players are on the roster bubble. Cornerback Cam Lampkin, offensive lineman Bill Murray, running back Jarquez Hunter, wide receiver Tyler Scott, and edge rusher Wesley Bailey are all fighting for their spots. The status of defensive tackle Aaron Donald also looms large; the team is preparing for scenarios with and without his potential return, which would impact roster decisions on the defensive line.

The Chargers, too, are dealing with roster implications, particularly on the offensive line. With the injury to center Tyler Biadasz, rookie Jake Slaughter is being pressed into action and needs to build chemistry with quarterback Justin Herbert. The competition at left guard and versatility at tackle are also areas to watch.

While many established starters for both teams are expected to sit out or play minimally, the preseason finale remains a critical evaluation period for players on the fringe and those competing for starting or backup roles.
