IRVING, Texas -- Dallas Cowboys coach Jason Garrett did not offer up a timetable on when or if the team will make a quarterback change, but he does not want to make a decision based on the emotions of Sunday’s 30-6 loss to the New England Patriots.

After the game Sunday, Garrett was asked specifically if the quarterback spot would be evaluated as to who would start Oct. 25 against the New York Giants and responded, “Yes.” On Monday, Garrett spread the evaluation process to the whole roster.

“I don’t want to get into the whole thing,” Garrett said. “We’re going to evaluate our quarterbacks, we’re going to evaluate our offensive line, we’re going to evaluate our tight ends, our receivers, our running backs, everybody on defense and everybody in the kicking game. We’ll do that this week and we’ll make any determination as the week goes on.”

Brandon Weeden struggled against the Patriots, completing 26 of 39 passes for 188 yards and an interception. He was sacked three times and the offense put up a season-low 264 yards on 66 plays. The Cowboys failed to score a touchdown for the first time since Week 3 of the 2011 season when Tony Romo was playing with a punctured lung and cracked rib in an 18-16 win against the Washington Redskins.

Garrett said the coaches will look not only at how Weeden is playing but how the team has responded to Weeden.

“You look at what we’re asking him to do and how he handles that and then how he executes those plays on a consistent basis, week in and week out and you look at the overall production of the quarterback,” Garrett said. “The quarterback is one of those positions where you don’t isolate him. His impact on the offense is important. His impact on the football team is important. You put all of those factors together and you try to make your best judgment.”

Matt Cassel served as Weeden’s backup Sunday for the first time since being acquired from the Buffalo Bills. While Garrett said the Cowboys were comfortable with Cassel as the backup, they never considered playing him, even late in the second half.

“He’s worked hard, he’s a veteran player, he’s a smart guy, he’s been here for a little bit,” Garrett said of Cassel. “There are always levels of knowing something. The more you’re around something, the more experienced you are with the people doing it together, the better you’re going to be at it. But he’s certainly comfortable with our system.”
