I would guess that their non-adjusted numbers against the run (-26% - negative is good) are boosted by recovering 15 fumbles..
One thing of note, their statistical variance is slightly larger than the Saints defense.. So while our defense hasn't been the greatest - though they've been solid - they've been consistent and rank as the 4th most consistent defense..
FO.com does do opponent adjustments so SF's defense being ranked 6th is very solid. But it pales when you compare it to the #1 O ranking of the Saints in terms of degree.
SF weighted defense DVOA is -8.8%
NO weighted offense DVOA is 44.0%
So the Saints are much more above average than the Niners. Or said another way -- if you subtract the SF D from the NO O, you get the NE O which I for one will take!
As follow up to the WR comments, check out the SF pass defense rating against TEs --they are 20th in league. Watch for a BIG game from Graham.
