LA Chargers: 3 franchise records that could be broken in Week 18

2. Justin Herbert: Passing yards and passing completions

Justin Herbert set the franchise record for passing yards in 16 games, which is exactly how many games the record was set in by Philip Rivers. Now, with the benefit of having an extra game (in primetime, where he thrives, nonetheless) Herbert has a chance to set the other two most important passing records to give himself the best quarterback season in franchise history.

Oh, and did we mention that he is still only in his second year in the NFL and it is his first season in a new offensive scheme? Feels like that is an important thing to highlight as Herbert is putting together a record-setting season.

Herbert is 172 yards away from breaking Dan Fouts' franchise record for passing yards in a season. The record is currently at 4,802 and while it is a bit of a longshot, it certainly is possible for Herbert to become the first 5,000-yard passer in Chargers franchise history. Herbert would need 369 passing yards to hit the 5,000 mark. He has hit that total twice this season.

The other record that Herbert could beat, which is harder than the passing yards, is passing completions. Rivers has the record for completions in a season with 437 in 2015. Herbert needs to complete 29 passes to break Rivers' record. He has finished with 29 or more completions four times this season.

If Herbert has a truly massive game with over 369 passing yards and five passing touchdowns (not likely, but certainly not out of the realm of possibility with how good Herbert is) then he will have just the seventh season in NFL history with 5,000 passing yards and 40 passing touchdowns.
