Rapid Reaction: Jaguars 35, Cowboys 17

ARLINGTON, Texas -- The Cowboys are off to one of their worst starts in franchise history. The Jacksonville Jaguars beat up the Cowboys to the tune of a 35-17 victory at Cowboys Stadium on Sunday.

The Cowboys have issues on run defense, run offense and pass defense, and you have to wonder if the players are tuning out coach Wade Phillips.

What does it mean? Dallas' loss pushed it to 1-6 on the season and 0-4 at Cowboys Stadium. This is one of the worst starts for the first two months of the season in franchise history. Dallas started 1-6 in the 1963 season and 0-6 in 1960. A more recent bad start was 0-8 in 1989.

Jon Kitna gets the start: Making his first start since the 2008 season, Jon Kitna was picked off four times with no touchdown passes in the loss. Kitna completed 34-of-49 passes for 379 yards. His quarterback rating was 64.9. Kitna could have had five picks, but a penalty negated another interception.

Run defense: The Cowboys have struggled to stop the run. Maurice Jones-Drew rushed 27 times for 135 yards. It marked the fourth time this season the Cowboys have allowed a runner to gain at least 100 yards in a game. Dallas gave up 200 rushing yards in the loss to the New York Giants.

Health issues: Cornerback Terence Newman didn't finish the game because of an apparent injury to his ribs, bruised in the Monday night loss to the Giants. Also, running back Felix Jones suffered a bruised left forearm; X-rays were negative and he did finish the game.

Phil Costa starts at left guard: With Kyle Kosier out with ankle problems, Phil Costa got the start and struggled most of the afternoon. Costa was slow getting to his blocks when he had to pull and didn't have any power at the line of scrimmage.

What's next? Does it matter? The Cowboys visit Green Bay next Sunday.
