The Steelers offense isn't the same without Rashard Mendenhall, who has struggled with injuries during his time in Pittsburgh. Miller has ideal size for an NFL back, excellent vision, and explosiveness to the hole. He has a second gear to outrun defenders in the open field, and keeps his legs moving after contact. His pass blocking will need some work at the next level, but he offers a quality back to compliment Mendenhall, and an insurance policy in case Mendenhall is injured.
