Dallas Cowboys head coach Jason Garrett was expecting a little better of a performance out of his team on Sunday.

The Cowboys lost to the San Francisco 49ers, 23-6, in somewhat of a dismal effort. Garrett hammered his team during the postgame, via the Fort Worth Star-Telegram.

“It wasn’t very good on offense," Garrett said. "It wasn’t very good on defense. It wasn’t very good kicking game. It wasn’t good early, middle or late. It wasn't a very good performance at all.”

Not many of the starters played in the contest. In fact, the offensive line was without three key starters which could partially explain the lackluster offensive performance.

“No excuses. We’re going to evaluate the game,” Garrett said. “We’re going to evaluate the guys who played in the game and from my vantage point, we didn’t play very well. We’ll watch the tape and try to find some of the positive things and build on those and address the negative things. When you’re out there you have a responsibility to play to a certain level. Period. The standard we set is high and we’re looking for guys to play to that standard. We didn’t get enough of that tonight.”

Running back Joseph Randle averaged 4.3 yards per carry on seven attempts which wasn't bad at all. And running back Gus Johnson chipped in 24 rushing yards in the fourth quarter. But other than that, the rushing attack was underwhelming along with some other areas from the game.

“We didn’t run the ball very well, obviously,” Garrett said. “First series wasn’t very good. Second, third and fourth series weren’t very good. Obviously, we were trying to control the line of scrimmage and didn’t do a very good job of that. It’s hard for me to make specific assessments, I have a bad angle on the sideline, but we obviously weren’t successful running the football, moving the football, making first down. We turned the ball over on offense, we didn’t get any takeaways. Got a punt blocked. Weren’t consistent in our execution in any of the three phases. Just really didn’t play well.”

There were still a few bright spots for the Cowboys. Most notably, the defensive line was excellent as the unit collected five tackles for losses and three sacks.
