The Chargers aren’t expected to deploy their starters, so we’re likely going to see a healthy amount of Trey Lance. That may be good in this spot. Lance - who was drafted by the 49ers in the first round of the 2021 NFL Draft - now gets a chance to somewhat settle the score.
The injury-riddled 49ers are also not expected to feature starters. Behind Purdy are banged-up Mac Jones, Carter Bradley, and Nate Sudfeld, who the team just signed this week as it navigates the depletions to the quarterback room. While Sudfeld is no stranger to San Francisco, it’s a concerning sign for the 49ers’ depth.
The Chargers may not care about winning this game, but Lance certainly does.
He told reporters after last week’s defeat that he wants to go out and win against his former team. That isn’t much of an edge, but it is enough of one for me to have some confidence in the Chargers, and it helps that San Francisco’s roster is so banged up.

💰 Chargers vs. 49ers best bet

1️⃣ Chargers First Half -0.5 ⭐⭐⭐
📊 Best odds: -105 via Betway ($10 to win $9.52)
🔢 Implied probability: 51.22%

The reasoning for this bet is essentially the same as for the last, but we specifically want to minimize the risk of bad possessions from Los Angeles’ final quarterback, DJ Uiagalelei. The former Clemson, Oregon State, and Florida State starter appeared in just five games for the Seminoles last year and completed 53.8% of his passes with four touchdowns and six interceptions.
Uiagalelei hasn’t been bad in the preseason, but offensive coordinator Greg Roman doesn’t ask very much of him as a passer – in five drives, Uiagalelei has attempted four passes. Uiagalelei’s drives all came deep into games, well into the second half, with Roman refusing to give him the ball until the fourth quarter.
We would rather take our chances with Lance and Taylor Heinicke than the full Los Angeles quarterback room. With both Purdy and Jones unlikely to play, the Chargers tandem we’re likely to see in the first half has a huge leg up – both in experience and motivation – over the counterparts we’re likely to see from the 49ers.
