From LZ's blog:
I think the scheme isn't terrific. One person I speak with who works for a team the Texans play told me that they were very easy to figure out on defense and that "nobody in the secondary worries you at all".
This is the coordinator that Kubiak is content with leading the defense. The secondary are a group of backs that Kubiak is content with having them on the field.
He's digging himself a grave for a funeral that no one is going to.
