It's no secret that the Raiders hold the 2nd longest losing streak in the NFL vs the Chargers. Only the Bills have lost more games to a single opponent (Patriots-14). On paper it looks to be an easy win for the Chargers, as it has been for 7 years.
The Raiders need this win to stay in contention for the AFC West. More importantly, they need this win to avoid a catastrophic meltdown. However, there are factors that could help get the holy "W" over the Chargers.
