There’s a real possibility when the Pittsburgh Steelers and Los Angeles Chargers square off, Chargers quarterback Justin Herbert won’t be in the starting lineup. However, head coach Jim Harbaugh isn’t ready to commit to either backup quarterback should Herbert be unable to go.

The Pittsburgh Steelers head into a test of wills against the Los Angeles Chargers. In many categories, these teams are ranked first and second defensively, while they both want to run the ball at will against other teams. Pittsburgh might have one key advantage against the Chargers, though.

In Week 3, there's a very good chance that changes, as Harbaugh has shown he's willing to commit to the run to a comedic degree, and with Herbert injured, the team may exceed its 35.5 rushing attempts per game, even if the Steelers' defensive front is a whole heck of a lot harder to run against than the Las Vegas Raiders or the Carolina Panthers.
