"I will be talking to people (candidates) as soon as I can," Kubiak said. "I've known Wade a long time. I've competed against him. I have a lot of respect for him. I think it's safe to say that Wade will be a candidate."
The interest is mutual.
"Yes, I am interested," Phillips said. "I know the owner (Bob McNair) and coach. I like them, and they're guys I'd like to work for."
In addition to Bush, the Texans fired linebackers coach Johnny Holland, assistant linebackers coach Robert Saleh and defensive backs coach David Gibbs on Monday. Kubiak said the new coordinator would have input into hiring a defensive staff and the scheme.
Phillips is no stranger to Houston, where he played and coached at the Univeristy of Houston and served as an assistant under his father, Bum Phillips, with the Oilers. Bum Phillips said last week that his son wanted to continue coaching in the NFL.
