Am I happy? No, but I am more optimistic today that I was before the game.
I said before the game this would be a test to see if the defense is for real of it they were just taking advantage of bad offenses. Yes, they gave up 26 points last night and 3 TDs, but 20 of the 26 points came in 1 quarter when the Cowboys played give-away. I mean if not for a stupid offsides penalty, one of those TDs comes off the board. This wasn't just any team, the Eagles have on of the best offensive lines in the NFL and the Cowboys sacked Hurts 4 times.
So the Cowboys defense should be able to stand up to any offense in the NFC.
On the other side, when Dak comes back they should be better on offense. But they need another WR.
