Wade Phillips doesn't expect to be a head coach again in the NFL, but he's happy to be Houston's defensive coordinator. Phillips reported to work with the Texans for the first time on Monday. He was hired last week, two days after Kubiak fired defensive coordinator Frank Bush. Phillips, 63, was fired as the head coach in Dallas after the Cowboys started 1-7. His career record is 83-64, but he isn't anticipating any more head coaching offers coming his way. "It's perception, sometimes, more than reality," Phillips said. "I've won a lot of games in this league and I have a really high winning percentage. I don't see me being a head coach again, because of the perception overall. "When you get fired, it's usually, 'Hey, he was fired because he can?t win,' " Phillips said. "It wasn't 'cause I couldn?t win. I couldn't win enough."
