The San Diego Chargers move up two spots to No. 17 after an impressive win at home against a talented but inconsistent Dallas Cowboys squad.

Now sitting at 2-2, the schedule continues to turn in San Diego’s favor. The Chargers face a dinged-up Oakland team on the road on Sunday, then return home to take on Indianapolis (Oct. 14), and close out the month on the road against hapless Jacksonville (Oct. 20) before the team’s bye week.

All three of those games are winnable. But the Chargers have to keep competing with the same urgency they played with against Dallas, particularly on the defensive end. Through four games, the identity of a Philip Rivers-led offense has been established. The Chargers need to create a similar type of mindset on the defensive side of the ball.
