It's the red zone. And the lack of production in the red zone to be more precise.
Four times the Cowboys marched within Oakland's 20 yard line, and four times the Raiders held Dallas out of the end zone.
Dallas also held a 9-0 lead in the fourth quarter before giving up 17 consecutive points to lose the game, gave up four sacks, including three on the opening drive and had two turnovers.
Head coach Wade Phillips said afterwards he was surprised at the outcome, among other things.
"I tell you what I told the team: this proves we have more work to do," he said. "I'm not happy obviously with the results. I thought we played more like the first preseason game than the second one in some areas. I thought we had complete control of the game and lost in the fourth quarter."
The only good news that came out of the loss was the continued consistency of kicker David Buehler, who has now made 6-of-7 field goals in two games.
Dallas quarterbacks were also productive, again outside of the red zone, as Tony Romo was 4-of-7 for 52 yards and backup Jon Kitna was 8-of-11 for 96 yards.
Still, the red zone issues were on the mind of everyone in the locker room afterwards.
"Absolutely we're out here to score put points on the board and get touchdowns," Romo said. "The execution has to be, there's a fine line you don't want to show the stuff that we've been doing, but at some point we have to get it in and get better. We go back this week and get to Oxnard and we're going to work our butts off to get better."
Jason Campbell made his debut under center for the Raiders and was only 7-of-13 passing for 46 yards and never came close to leading a scoring drive.
Oakland took its first lead 10-9 with 2:24 left when Sebastian Janikowski connected on a 28-yard field goal.
Raiders safety Jerome Boyd added to the lead when he intercepted a pass and returned it 48 yards for a touchdown with 33 seconds left off a deflection.
