DeMarco Murray sat out the first four days of OTAs over the course of two weeks to protect his hamstrings, but sources tell FOXSports that the oft-injured running back did do limited "individual work" at Wednesday's Dallas Cowboys practice. Maybe that "limited work" is a step towards Murray reaching his potential, which he and the Cowboys think is virtually unlimited. "I am going to play all 16 this year, and I'm excited," Murray said this week, predicting an injury-free season. "It's going to be a great year for us.” The playoffs could be in reach for Dallas if Murray -- who joined the Cowboys as a third-round pick in 2011 already carrying the "injury-prone" label – achieves that first goal.
