Where NFC West teams rank: Week 16

The San Francisco 49ers maintained the NFL's top-ranked rush defense in yards allowed despite Marshawn Lynch's 107-yard game against them Saturday.

They have allowed 250 fewer yards on the ground than second-ranked Baltimore. This would be San Francisco's first No. 1 ranking against the run since 1995.

The charts reveal updated rankings across 10 categories. The 49ers' defense moved up three spots to No. 2 in Total QBR allowed. Teams with higher QBR scores than their opponents have gone 47-1 over the past three weeks.
