While the collapse of the Steelers offense last year was largely due to Ben Roethlisberger's injury, the lack of spark provided by the backfield committee of James Conner, Benny Snell and Jaylen Samuels was hard to ignore. Enter McFarland, a fourth-round pick out of Maryland who ran a 4.44 40-yard dash at the combine. McFarland's acceleration and agility make him dangerous in the open field, and while he may lack the power and vision to make an impact between the tackles, Pittsburgh already has plenty of options on the roster to handle those duties, and he'll be running behind an offensive line that won't make him work too hard to find holes. He also needs to sharpen his blocking and receiving skills if he wants to emerge as a consistent third-down weapon. McFarland might not be ready to handle a large touch volume, but he offers the Steelers big-play upside that even a healthy Conner can't match.
