I never thought I would say this but I think our defense is missing Terrence Cody. He was fantastic in the pre-season being ranked among the top defenders on the team. Before his injury our run D was great. Now teams are able to run right up the middle with no issue.
Ngata has taken his spot at nose tackle and is bad. There is no denying it, he is not playing well at all. In addition to this Webb needs to step up. I understand he is coming back from injury but he hasn't been playing well at all. He has gotten lucky a few times with overthrown balls and drops.
I think after the bye when Cody returns our D will be much better. He had that kind of impact the first few games.
