The Baltimore Ravens (1-0) and Dallas Cowboys (0-1) face off in each team’s second preseason game Saturday night at AT&T Stadium in Arlington, Texas. 1. Efficiency of quarterback Joe Flacco. In the season opener last week, Flacco looked like a quarterback who had been in new offensive coordinator Gary Kubiak's system for years. He was decisive and precise on his intermediate throws, only throwing one incompletion on five pass attempts. Flacco has never been known as a high-percentage passer.via - NFL Nation
