Here we are almost halfway through the 2007 football season, and we still have no idea what the Cowboys' defense is all about.

The Cowboys are 6-1, seemingly on the way to their first NFC East title since 1998, although the Giants continue to win and somehow remain just one game out with one more head-to-head battle looming.

We know how effective the Cowboys are on offense. The passing game is explosive with Tony Romo (who's been hanging out more lately with Britney Spears than with Marcus Spears) chucking the ball up and down the field to Patrick Crayton, Jason Witten and Terrell Owens. And Marion Barber remains one of the NFL's most underrated tailbacks.

No issue there. No mystery. They can put up points in a hurry. But what about their defense? It's stout against the run, top-5 in yards allowed and yards per-carry. But the two times it has faced a real, live, ambulatory quarterback, it got shredded.

For the most part, the Cowboys have built their 6-1 record against a series of inept, inexperienced and injured quarterbacks. They've battered backups and routed rookies. And when they've faced a quarterback with any sort of track record, they haven't been able to slow him down.

When the Cowboys beat the Dolphins, they toppled 37-year-old Trent Green. When they beat the Bears, they saw Rex Grossman at his worst, just days before he was benched. When they beat the Rams, they got a combination of a wincing Marc Bulger, playing with two painful broken ribs, and journeyman Gus Frerotte, now stinking it up for his seventh NFL team in 10 years. When they escaped the Bills, they beat rookie Trent Edwards, making his second career start. And when they beat the Vikings, all they had to overcome was a woefully overmatched Tarvaris Jackson in his sixth NFL start and maybe his last one for a long time.

They have faced two healthy, experienced quarterbacks who weren't on the brink of getting benched: Eli Manning and Tom Brady. And those two combined for 700 passing yards, completed 68 percent of their passes, threw nine touchdowns and one interception and put up 83 points. Combined passer rating: 141.0.

OK, so Brady does this to everybody, point taken. But Manning doesn't. In fact, his 300-yard, four-touchdown performance against Dallas is the only one of his career. Since completing 68 percent of his passes with four TDs and one INT against the Cowboys on opening day, Manning has thrown nine TDs and eight interceptions and completed a pedestrian 56 percent of his passes.
