So it was nice of the kid to catch a 48-yard screen pass up the left side on the team's first play from scrimmage. We've seen the Cowboys use the screen game a lot this preseason, with Tony Romo throwing to starting running back Felix Jones, and it appears as though the Cowboys would like to use the weapons they have on offense to spread out the defense when possible and trade on their speed. Murray looks like a guy who can help with that. He looked excellent when they got him on the outside, in space, around the edge, able to pick up big chunks of yardage in those spots. That speaks to his athletic ability, which surely showed up on pre-draft tape, and wasn't really a surprise. What the Cowboys and their fans wanted to see from Murray on Thursday night was how Murray looked running between the tackles. With a little more than a minute to go in the first quarter, after picking up nine yards on first down on a run to the outside, Murray drove hard through the middle to pick up the first down on second-and-one.
