This article says he played for the Broncos when Kubiak and Smith were there. He also coached the 49ers DBs when they were one of the worst passing defenses in the history of the league. Yes, even worse than the 2010 Texans.
We'll see, I guess, but it's certainly not a hire that immediately makes you feel they'll improve just by his knowledge and presence.
Article also goes into why the Texans should sign Asomugha. It's fun to daydream, but fat chance of it happening!
