There is far more than 1 similarity based on the Chiefs game...by my count:
1. Lack of explosive plays down the field
2. Romo making a critical mistake
3. Defense can't get a stop late
4. Defense doesnt force any turnovers
5. No run game
6. Can't defend the middle of the field
7. Blown assignments on blitzes/stunts
8. Poor playcalling, particularly in the red zone
9. No draws/screens to keep the defense off balance
I dont disagree that the team has made some progress, but I would still say that this looks a LOT like like the same ol Cowboys. That bubble screen to Williams on third and goal from the 9 or whatever, was so Cowboys is freaking hurt to watch. The screen at the end of the game and the failure to even attempt another play was ridiculously Cowboy-esque. Completely abandoning the run game was utterly Cowboys.
Your list is so mish-mash, untrue, or repetitive.
1) We had a bunch of explosive plays downfield last year. So maybe less this year, but still different. And this is way too early to tell.
2) Romo didn't make a critical mistake in either game. He hasn't had one of those games where he clearly blew it or cost the team. Plus, Romo is the same. How can we expect that to be different? That's ridiculous. Garrett still has red hair, too. If Romo stays the same, and we fix other issues (penalties, turnovers, pressure, pass protection), we'll be better.
3) The Defense got a late stop in game 1. A couple of them. HUGE ones! And except for a bad call, they did in game 2 as well. Plus, the defense never gave up late stops last year because WE ALWAYS PLAYED FROM BEHIND. Again, this lack of playing behind is a big change so far this year.
4) Um, the defense is averaging three per game. I know they all happened in one game but this is not an argument for you yet. If you throw in pre-season, the evidence says you will end up being dead wrong here.
5) No run game -- gave you that already.
6) We didn't get killed in the middle of the field yesterday. The D played good. And they won the Giants game for us, besides keeping us in this one. Again, this is too early to proclaim "Can't." BTW, the entire NFL has some problems stopping the pass, in case you didn't notice.
7) Show me blown blitzes or stunts. In a new scheme, they are remarkably few. Pressure has been great. Great Run D, too. This is a definite improvement over last year so far.
8) Maybe poor playcalling in red zone, although I think you are basing this on one play call or one drive from this game. Again, the reason for this is we can't run. So, it's a big thing we haven't improved, but the many other things that are different are still different.
9) Which is it? Do we not throw down field or do we do it too much? DO we suck at screens and should stop throwing them (as many have said after the failures last game) or do we need to throw more? The over-reactors usually contradict themselves when you pay enough attention. Plus, this is a duplicate -- you already mentioned poor play calling. I don't know enough about what plays were called to judge this one. It's too subjective.
Facts are -- we have more pressure, better pass protection, more turnovers, more first half leads, less playing from behind, LESS PENALTIES THAN THE TWO TEAMS WE PLAYED AGAINST, we showed more in a tough week 2 road game, and Romo has been playing more conservative, less firing down field, less careless ball management. Plus we have yet to give up a big special teams play, I seem to recall 2 big ones made us lose in Seattle. There is AT LEAST as much evidence that things have changed. And it's way too early to tell for sure. But so far, my eyes see a different team. And the facts are on my side. Not the over-reacting hyperbole.
