Where NFC West teams rank in turnovers

Only the Pittsburgh Steelers have forced fewer turnovers than the Seattle Seahawks this season.

Pittsburgh has one. Seattle has two.

"We're trying to do everything we can, but when you don't affect the quarterback and you're not getting to him -- we didn’t get any sacks last week -- that’s where most of it starts," Seahawks coach Pete Carroll said Wednesday.

The Steelers are a league-worst minus-10 in turnover differential. They committed 11 total turnovers against Baltimore, Indianapolis and Houston, but none in their game against Seattle. The Seahawks have recovered none of their opponents' four fumbles. Studies have shown fumble recovery rates to be random, meaning Seattle should gain in this area over the course of the season. The Seahawks recovered 10 of their opponents' 22 fumbles last season.

Meanwhile, the San Francisco 49ers sit atop the turnover-differential standings, tied with Baltimore at plus-eight.

The Ravens collected seven turnovers against Pittsburgh in Week 1. The 49ers have forced turnovers at a more consistent pace, collecting three apiece against Seattle, Cincinnati and Philadelphia, and two against Dallas. They rank tied with Detroit and Minnesota for the fewest giveaways with three.

The chart shows where NFC West teams stand in turnover differential. The 49ers, Indianapolis Colts and St. Louis Rams are the only teams with fewer than two interceptions. Each has one.
