Let's look at who needs to step it up in the team's third preseason game in SoFi Stadium.

EL SEGUNDO, Calif -- Chargers quarterback Justin Herbert will make his preseason debut Saturday against the Rams. Harbaugh said he expects starters to play up to eight plays, but said not every starter will hit that number in the game, which will be the Chargers' third of the preseason.

The Rams won't be playing their starters, but the Chargers will have Justin Herbert and some of their top players on the field Saturday.
