Cowboys beat writer Todd Archer on the team's running game: I believe you'll see DeMarco Murray go from a career-high 217 carries in 2013 to 250-plus in 2014 provided he stays healthy. He's not been able to play a full season yet, so there is concern there as well. But with an offensive line with three first-round picks and a defense that will need protecting, the wise thing to do will be to run more ... once they get the lead with the passing game. They can't win games 14-10.
Murray should benefit from OC Scott Linehan “growing the pie” offensively (i.e. more plays, and more rush attempts). His FP/touch was #14 among the top 60 running backs in 2013, so if he sees an increase from the 19.3 touches per game he saw last season (and stays healthy), a top 5 season is well within reach.
