Compared to the first four games in 2013, the Cowboys are allowing more yards per game this year (382.3 to 383.8), more yards per play (6.5 to 5.9), more yards per rush (4 to 5), more runs of 10 yards or more (11 to seven) and have fewer sacks (five to 14). The third-down defense is worse too, 32.7 percent to 46.7 percent this year.
So what exactly is better?
The Cowboys have more interceptions (five to four) and have allowed fewer pass plays of 20 yards or more (11 to 16). They are better in the red zone as well, allowing eight scores on 11 possessions compared to 10 in 13 in 2013. Take away two scores given up by the offense, and the Cowboys' defense has allowed 18 points per game.
"I think we're understanding how to play defense and trust me that is a work in progress," coach Jason Garrett said.
Timely, situational play has been their greatest strength.
Barry Church's interception in the second quarter against the
Tennessee Titans led to a touchdown and a 10-0 lead. A Rolando McClain interception in the fourth quarter led to a field goal to salt away the win.
Bruce Carter's pick-six the following week against the St. Louis Rams with 5:58 to play gave the Cowboys a 34-24 lead.
Morris Claiborne's awful game ended with a game-sealing interception with 1:02 left.
Last week against the New Orleans Saints, a Carter deflection ended up in
Justin Durant's hands for an interception. The Cowboys turned that into a touchdown and a 17-0 lead. After the Saints cut the Dallas lead to 31-17, the defense forced a third-down stop in the fourth quarter that led the Saints into an ill-fated punt. The Cowboys scored on the ensuing drive.

What I see that is a big difference is key moments in the games when a play has to be made this defense is making them, they are not allowing teams to drive the field late in games to tie or take the lead as we often did last season. You can play with all these numbers all you want but when push comes to shove are you making the big plays to kill drives when you need it the most?
