Every week, we'll grade the Cowboys on the three phases of the weekend's game.
The one saving grace from Sunday to prevent an F grade here was the performance of DeMarco Murray and his offensive line in the running game. There was no big run from Murray. Instead, it was a more impressive, legitimate six or seven yards a pop. Murray had all kinds of room to run all day. But he also fumbled, and Tony Romo threw three interceptions, including one in the end zone. It was ugly and one of Romo's worst games in recent memory.
Again, the 49ers moved the ball, but they also were given some really good field position thanks to the Cowboys' turnovers. The Cowboys' defense did make a few stops in the second half that led some of the most optimistic Cowboys fans think the game perhaps wasn't quite over yet. The defensive line performed fairly well, as evidenced by the linebackers having such big tackle days.
Special teams: B
Overlooked, but solid. That's the best we can describe the performance of the Cowboys' special teams. Dwayne Harris averaged 30 yards on two kickoff returns, Dan Bailey was perfect and punter Chris Jones averaged 52.5 yards on his two punts.
