There's no telling how the Dallas backfield would've shaped up had they not drafted Ezekiel Elliott with the fourth overall pick last Thursday, but what we know now is Alfred Morris and Darren McFadden aren't going to be all that useful in fantasy football this year.
I mentioned Zeke as a big winner already -- the Cowboys are going to use him given what they invested, and we saw last season that very ordinary running backs can run behind that offensive line. After all, the team had nearly identical numbers on the ground in 2015 versus 2014, aside from volume.
It's obvious though: as long as Elliott is healthy, he's getting the near-60% market share in that backfield. That means little relevancy for Morris and DMC.
