Pittsburgh Steelers running back Najee Harris knew that the team wanted to find another runner to lighten his load a bit after he led the NFL during his rookie season with 381 carries. He just had no idea who it would be. Neither, it seems, did the Steelers. After all, they signed no notable veterans in free agency, nor did they draft one.
They did retain Benny Snell Jr. and Anthony McFarland Jr. from prior rosters, but who was going to emerge? Jeremy McNichols? Max Borghi? The reality is that we could have asked the same incredulous question about Jaylen Warren, a rookie college free agent, back in June.
