"The guys blocked," Harbaugh said. "Ray Rice and Willis McGahee ran hard, and I think we had more broken tackles than we’ve had. The offensive line works hard every day, and sometimes you don’t see the fruits of their labor quickly. I think we get a full 60 minutes effort-wise, but sometimes, we haven’t made the plays we’ve had to make. But this is a tough league and [New Orleans] is a tough football team."
