They drafted Ezekiel Elliott fourth overall to be the lead back but have two other backs who can handle big workloads. In order to maximize -- or justify -- the selection of a running back that high, Elliott has to get a lot of work.
Can they keep McFadden and Morris happy? In his two years as offensive coordinator, Scott Linehan has relied mostly on one back to carry the load. First it was Murray, and last year, after Joseph Randle fell apart, it was McFadden.
The story quoted Linehan as saying he already trusts Elliott to be on the field in any situation and he thinks he's a full-package back, which means Morris and McFadden are insurance and/or role players. McFadden will not be ready for camp and Lance Dunbar is likely headed for the PUP list despite recovering quicker than expected from a torn ACL, but is more of a third down back. These are all reasons Elliott is one of the top backs to draft this year.
