Cowboys RB Joseph Randle averaged 6.7 yards a carry off the bench in 2014. He can average well over 5.0 getting 20-plus carries a game as a starter as long as he plays with the discipline that DeMarco Murray sometimes lacked.
Randle’s only obstacle to 1,500-plus yards is Darren McFadden, a fascinating wild card in this backfield equation. In between hamstring pulls and ankles sprains, McFadden has proven to be an excellent straight-line runner. But if Murray is “plywood” on the stiffness scale, McFadden is “oak.” My good friend Greg Cosell of NFL Films once said it best: it’s like McFadden’s lower body and upper body are fused together. An inability to make people miss was something previous Raider coaching staffs didn’t like about the former first-round running back.
The article goes on to say that McFadden might end up being the better fit since Randle's elusiveness may lead to him making poor decisions in the running game. Randle was highly effective (6.7 YPC) in 2014 and is reportedly showing more maturity after several off-the-field issues. He's not going to see a DeMarco Murray-type workload, but 225-250 carries is feasible if he wins the lead back job, and it appears he will.
