Justin Herbert, who dealt with a plantar fascia injury that kept him out all preseason, has been hobbled with an ankle injury. On Friday, it was revealed that the injury is actually a high ankle sprain.

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.

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.
