Jon Kitna tries to improve

IRVING -- Jon Kitna made his first start since Week 4 of the 2008 season on Sunday vs. Jacksonville.

Kitna completed 34 of 49 passes for 379 yards with one touchdown and four interceptions, three of which came off receivers hands.

"Not good enough," Kitna said. "Early on when I started playing in this league I had a guy, Glenn Foley, tell me, quarterbacks get an A when you win and an F when you lose regardless of what the stats look like. That’s kind of the way I view it. You’ve got to play better when you lose."

In his career, Kitna is 46-70 as a starter and he takes a 1-5 record into the Packers game, the Cowboys opponent, Sunday.

One of the things Kitna had trouble with when he replaced Tony Romo in the Giants game two weeks ago was finding a rhythm. He looked rusty in the third quarter of that game and looked better in the fourth quarter.

Sunday vs. the Jags, Kitna's first play was a nine-yard pass to Dez Bryant and he completed his first three passes before misfiring a pass to tight end Martellus Bennett.

It seemed Kitna was a little more comfortable at the start of the game on Sunday, it just didn't carry over the rest of the way.

"I don’t know," Kitna said. "Again, I’m pretty comfortable in the system. What we need to do is continue to do is find the things we’re doing really well and hang our hat on those, regardless of who is playing quarterback. That is one thing you have to try to do when you’re in a funk like this. What are we doing well, let’s emphasize those things."

The 49 pass attempts were the most for Kitna since he threw 41 passes in a 48-25 loss to the Green Bay Packers on Sept. 14, 2008.
