I can understand losing to San Francisco and Philly, but there was no excuse for what happened against AZ. We would be within striking distance if it wasn’t for that loss.
Oh, there's excuses, I can list some below:
1. No familiarity with Dobbs, didn't know how he could play.
2. Took the game for granted with no Murray playing.
3. Cowboys weren't as good as they are now.
4. Beat a Giants team 40-0 and got overconfident.
Now I'm not saying any of the above are valid. Just noting that you can always find excuses.
Though you really don't need an excuse, or even a reason, for "what happened against AZ". Losses like that happen to every team. Nothing unusual there.
If it happens several times during one season, that's another thing. But so far Dallas has handily handled (cute, huh?) all other "weak" teams, so I'll write that game off as an aberration....
