Jerry Jones: 'We have faith in defensive system'

Dallas Cowboys owner Jerry Jones has insisted that the club are going to stick with the defensive system of coordinator Monte Kiffin despite their struggles this year.

The Cowboys have adapted from the 3-4 system used by Rob Ryan last season to the Tampa 2 used by Kiffin in his days with the Tampa Bay Buccaneers, which guided them to a Super Bowl victory in the 2002 campaign.

"This is the system we want to be in going forward," Jones told the Fort Worth Star-Telegram. "Nothing about this year has discouraged us from this system."

Dallas have to beat the Philadelphia Eagles on Sunday to reach the post-season.
