Dallas' future at RB

When healthy -- and that's a big qualifier -- DeMarco Murray has been a game-changer at the RB position for the Dallas Cowboys. But, his injury woes have forced them to examine other options, and they cast a shade over his future with the team after his rookie contract expires after the 2014 campaign. This offseason, the club added Joseph Randle in the fifth round, and signed Kendial Lawrence as an undrafted FA; both men may have a significant impact on the future of the position for Dallas.
