Sometimes, you really get a sense of how valuable a player is to a team when he’s not on the field for a while. That’s been the case for Los Angeles Chargers receiver Mike Williams, who has missed four full games this season with injuries, and has played 675 snaps to 460 off the field. When Williams is in the game, the Chargers’ passing EPA rises from -0.08 to +0.04, their average depth of target jumps from 5.8 to 6.7, the team’s catch rate goes from 68.5% to 72.1%, and Justin Herbert’s EPA per play goes from 0.02 to 0.12.
