2013 Outlook: Murray has missed nine of 32 NFL games with leg injuries. It's too early in his career to call him soft -- after all, his rookie campaign was cut short by a broken leg -- but the fact is that Murray arrived in Dallas with a collegiate reputation for missing time. When he's out there, Murray fills out the uniform impressively: At 227 pounds he can play the banging role but he's also nimble in space with very good hands. Sixteen games of starting work for Murray would likely result in a superstar season. Maybe his third year will be the charm.
2013 Outlook: Dunbar went undrafted last year because of size concerns; at 5-foot-8, 191 pounds, he's on the small side. But when DeMarco Murray went down in October, Dunbar's practice-squad work paid off with a call-up to the active roster. He played well on kick returns, and in November moved past Phillip Tanner on the RB depth chart. During OTAs and training camp, Dunbar passed rookie Joseph Randle on the depth chart, but then suffered a foot injury that has him questionable for September. Should Murray get hurt again, we're probably looking at a Dunbar/Randle combo.
2013 Outlook: Randle was a wildly productive collegiate player, but expectations should be tempered. He played in the Big 12, where defenses offer only occasional resistance, and he's coming from Oklahoma State's spread offense. A thin, upright runner with good receiving skills, Randle fell behind Lance Dunbar early in training camp, though Dunbar hurt a foot and could miss time in September. Regardless, though, should Murray get hurt, we'd probably be looking at a platoon of Randle and Dunbar.
