September, 9, 2013 Sep 9 11:00 AM ET By Calvin Watkins | ESPNDallas.com http://espn.go.com/blog/dallas/cowboys/post/_/id/4714502/offensive-line-with-mixed-night ARLINGTON, Texas -- The Cowboys offensive line had two players make their debuts on Sunday night against the New York Giants. Rookie Travis Frederick, the Cowboys' first-round pick, started at center, and second-year right guard Ronald Leary earned his first career start. The Cowboys rushed for 87 yards and saw quarterback Tony Romo get sacked twice and he suffered an apparent rib injury late in the first half after two defenders hit him. The line also gave Romo some time to throw 49 passes for 263 yards and two touchdowns. On one of Romo's sacks the quarterback held the ball a long time and maybe should have just thrown the pass away. "It's never as good as it is and it's never as bad as you think it is," Frederick said of the line play. "You just got to watch the film and correct it. We ran the ball but I don't think we ran the ball as well as we wanted to. It's something we need to continue to work at and continue to improve."
