The Dallas Cowboys need a running back. There are many reasons why the above statement is true. For one, they only have three on the entire roster. Simply for training camp purposes, that’s not enough bodies.
For another, current starter Ezekiel Elliott has led the NFL in rushing attempts in two of his three seasons. Both times, he eclipsed 300+ carries. The one year he did not, he amassed 242 carries in just ten games.
Currently Elliott is 32 carries short of 900 in his very brief career. This does not take into account the number of receptions (135) or sheer number of plays in which he is a participant.
