"Even as speculation increases that he could be in line for a head-coaching job after the season, Rob Ryan said Friday he remains focused solely on helping the Dallas Cowboys win a Super Bowl.

"That's the only thing we're here to do is to try to win championships. That's what we're going to do," the defensive coordinator said Friday.

"About the speculation, I mean, shoot, I've speculated my whole life. It's no big deal. Those opportunities come when you work hard and take care of the job you have. That's what I am trying to do."

Several media outlets bandied Ryan's name about after Jacksonville fired Jack Del Rio this week. Other coaches on the hot seat as the regular season winds down include Philadelphia's Andy Reid and San Diego's Norv Turner.

But in his weekly appearance with the media at Valley Ranch, Ryan insisted his attention hasn't been diverted from helping the NFC East-leading Cowboys (7-4) beat Arizona (4-7) on Sunday.

Ryan won two Super Bowl rings as New England's linebackers coach from 2000-2003.

"There are some great feelings in the world, some great experiences," Ryan said. "Having kids is a great experience. Marrying the right girl is a great experience. Winning a Super Bowl is something else. It's hard to say what's better ... That's what we want to do.""
