Through two weeks, the Pittsburgh Steelers have only allowed 16 points. Last week the Steelers held the Denver Broncos to just six points. Only one team has allowed fewer points through two games. That would be this week's opponent, the Los Angeles Chargers.

The Steelers and Chargers square off this week in a battle of the nine remaining undefeated teams and the two best scoring defenses in the league. For the season, Los Angeles has only allowed 13 points.

While being No. 2 in points allowed, the Steelers are No. 5 in yards allowed through two games. The Chargers are tops in points allowed under new head coach Jim Harbaugh and are No. 2 in yards allowed as well.

Both of these teams want to pound the football on the ground and play tough defense. If you are a fan of old-school, smash-mouth football, this could be the game to watch this weekend.
