OAKLAND -- You can find a lot of wrong things from the Cowboys' 3-0 victory over the Oakland Raiders on Monday night, and having 12 penalties for 91 yards is one of them.

"They hurt us and obviously it's an area we need to improve throughout our entire football team," coach Jason Garrett said. "Special teams early on hurt us. We gave them two possession opportunities after we made two good stops on defense."

Special teams was called for four penalties. Jamize Olawale ran into punter Marquette King and Teddy Williams was called for offsides, giving the Raiders a first down.

The offensive line was called for five penalties, including two false starts, and there was a bad substitution penalty on the last play of the game when the Cowboys were trying a kneel down.

"Each of those is a case (where) a young guy is trying to do a little too much," Garrett said. "Running into the kicker, Teddy being offsides giving them a first down when they’re punting, and obviously that’s line one, you can't give them the ball back in those situations. Those guys are trying to make a play and sometimes you got to play with poise, do your job, let the game come to you a little bit, and I thought those guys came back as the game wore on. But overall there were too many penalties, and it hurt our team."
