The Cowboys offense has some serious issues, and I'm quite sure T.O. is not the largest problem (contrary to popular belief). There's not a lot of swagger, and Romo (the engine to that team) looks indecisive, and is a turnover machine. I think the media can stop nut-suckling this guy, now. After reading his body language for 3+ games, I'm not sure he's going to be able to handle the pressure-cooker he's heading for this year.
To piggy-back on Alex's comment, the Cowboys defense has still not been "fixed" by "Mr. Fix-It", which was the whole reason he was hired in the first place (and he readily admits as much, hence giving himself the nickname).
The talent is there. Newman (1st round), Henry (FA), Hamilin (FA), R. Williams (1st round), Jenkins (1st round), Pack (FA), Tank (FA), Ware (1st round), Spears (1st round), Canty (4th round), Thomas (FA), Ellis (1st round), James (4th round), Burnett (2nd round), Carpenter (1st round), Spencer (1st round)...That's a lot of high-end draft picks and FA "playmakers" that don't make plays on a consistent basis.
IF "Coach Fix-It" wants to buy himself one more year as head coach, he'd demote Stewart and take over the defense, because if Jerry's expectations aren't met this year, or if his team has a couple more Washington-type meltdowns this year, he won't hesitate to make the switch to the Red-Headed Genius as early as this off-season.
For those Cowboy fans looking at this through rose-colored glasses, we are essentially in 3rd place in the NFC East a little over a 1/4 of the way through the season. We've beat Cleveland, Philly, Green Bay, and Cincinatti. In retrospect, that's not real impressive, now, is it? The most that will make it out of the division is three teams. Is it out of the realm of possibility to think that we will lose AT Washington and AT Philly and only split with the Giants? We better beat the teams we're supposed to beat (i.e., Cardinals, Rams, Seahawks), and hope we have this defense fixed with the offense running more smoothly, otherwise, it's not out of the realm of possibility that we finish last in the East with a winning record and better record than one or two division winners and STILL not make the playoffs.
You cannot underestimate how big that loss was last week. They needed to take care of business in their own home, especially in this division. They didn't. Now they're behind the 8-ball. They need the mental toughness to come through this thing, and I'm pretty sure this teams' strength is not mental toughness.
