NFC West QB play mostly on rise lately

The past few weeks have been mostly better ones for NFC West quarterbacks.

The San Francisco 49ers' Alex Smith completed 18 of 19 passes with three touchdowns in Week 8.

Seattle Seahawks rookie Russell Wilson has seven TD passes with one interception over his past three games.

The St. Louis Rams' Sam Bradford just completed 26 of 39 passes for 275 yards and two scores against the 49ers, including the go-ahead touchdown pass late in regulation.

Arizona Cardinals quarterback John Skelton played arguably his best game of the season against Green Bay in Week 9, posting season highs in Total QBR (41.1) and yards (306) while taking only two sacks, down from 11 over his previous two games.

The chart ranks NFL divisions by Total QBR over the past three weeks. The NFC West ranked last at 46.6 through Week 7. It has ranked first over the subsequent three weeks. The NFC East, which ranked first at 65.2 through Week 7, ranks last at 42.0 over the past three weeks, in part because Eli Manning has struggled.

The column labeled "action plays" shows how many plays quarterbacks did something other than hand off or spike the ball. "FD" refers to first downs. Sack rate is calculated as sacks divided by the total of sacks and pass attempts.
