Let’s work under the assumption that RB Ezekiel Elliott's suspension ruling will be upheld and he will miss the next six games. Alfred Morris and Darren McFadden will get chances to make up for Elliott’s absence, but I wonder if Rod Smith ultimately can do more than anybody currently knows.
Smith was productive in the spring. He had a strong summer. He ran hard in the preseason. He has been the third-down back the last two games.
It’s odd to project somebody with four carries for 13 yards in his career as a lead back. Plus, he was never the guy at Ohio State either (549 career yards). But Smith has ability. He might be the most similar to Elliott among the Cowboys’ runners, but Smith doesn’t have the pedigree of Morris (three 1,000-yard seasons) or McFadden (top-five pick, the NFL’s fourth-leading rusher in 2015).
Obviously the author is just wondering out loud, in type. However, it may be something to keep in the back of your mind. It's also probably not what fantasy owners of Morris and McFadden want to hear - a possible third option to replace Elliott. Right now, Smith is a stash option.
