The Cowboys know they are good on defense. They rank fourth in the league overall and first against the run.
And if you don't believe the stats, just ask their cocky and confident defensive coordinator Rob Ryan.
It's one reason why he's looking forward to Sunday's game against quarterback Tom Brady and the New England Patriots high scoring offense.
Ryan's can't wait until game time to face what he calls the ultimate challenge.
"This is the ultimate challenge," Ryan said. "Our guys are excited. We've got a defense on the rise here and really can't wait for this game."
Ryan's knows the Patriots well because he coached there from 2000-2004 and was part of three Super Bowl title teams in 2001 and 2003 and 2004.
He's also confident because of his past success against them. It was Ryan's Browns defense in 2010 that was the last team to throttle Brady and the Patriots offense in a 31-14 victory. The Patriots have scored 30 or more points in the 13 games since.
The Cowboys, who have been off since the 34-30 loss to the Lions, studied that game plan night and day for the past two weeks. They have had added some wrinkles. But Ryan feels best about the upgrade in talent he has to work with in Dallas than he had in Cleveland last year.
The Cowboys are also healthy than they have been all season with the return of cornerback Orlando
Scandrick from a sprained ankle.
"New England is the best in football. That's clearly documented; it is every year," Ryan said. "But the bottom line is we know we're good and we're going to get better. We had the open week to get better with what we do, and we looked at New England now. And we're ready to play.We've got great players here and we're looking to prove it on Sunday."
