No actually opposite. Hurd was a power back that could move enough. He had a slow start but would make up for it when he hit his stride. Dont know how you can even think to consider him "a smaller version of jalen hurd." I loved jalen hurds ability. He was a bruiser and had enough body movement to shake a few guys and then he was gone if he got a few steps under his feet. However, i do side with him that he was better suited to be a tight end. Z. Knight is very shifty has a quick start but doesnt hit a very fast top speed. The running styles between the two are completely different.
