A periodic look at where NFC West defenses rank and potential areas to address:
Arizona Cardinals: No complaints here after holding Tom Brady to 18 points and Michael Vick to seven.
St. Louis Rams: Chris Long collected two sacks against Chicago, but the overall production has lagged. That needs to change with two home games coming up.
San Francisco 49ers: The 49ers opponents have scored touchdowns on all five trips inside the red zone. That is stunning. San Francisco' allowed its fifth red zone touchdown in Week 6 last season.
Seattle Seahawks: While the Seahawks limited Tony Romo and Aaron Rodgers to 19 points, they watched those QBs combine to convert 14 of 28 times on third down.
