The Los Angeles Chargers have little to play for in Week 18 against the Denver Broncos. While they could choose to jockey for playoff positioning, they are locked in as a Wild Card team in the AFC. Additionally, there is always the chance that a loss to the Broncos secures them their ideal first-round matchup.
Therefore, the most likely scenario is that Justin Herbert, who is still nurturing the hand injury that threatened him after the bye week, gets the chance to rest.
This would leave backup quarterback Trey Lance with the prime opportunity to prove his value ahead of his free agency this offseason.
