I don't know the criteria to measure the rankings on DVOA or OVOA, but some can be impossible with their standards. I heard a sports "analyst" (I can't remember his name but he is a well known commodity on the network) from ESPN that was having a conversation about the Seahawks with Jamele Hill (sweet God help me) and he said that the defense is borderline anemic stated it showed against the Rams. He stated Keenum "threw bombs over the top" to defeat us.
Everyone does realize we kept them to 208 yards of total offense, right? Without Jordan Hill, without Kam Chancellor, and they had a defensive TD. The defense, in my opinion, did just fine. It was hardly their fault the Rams only had a couple dozen yards to go several times due to three Seahawks turnovers.
Defensively this year, overall, we've been pretty solid. Not as dominant as the past two years, but pretty solid nonetheless.
