Mewelde Moore has achieved most of his success on the ground through two starts out of passing looks. He did have some success out of power sets on running downs in garbage time yesterday, but this is not a guy whom you can line up in the "I" and make consistent yardage.
That's why Willie Parker's healthy return is so important for this team. Despite dominating the game, the Steelers did not dominate time of possession against the Bengals. If Parker had returned this past week as his old self, the Steelers would have churned their way to a big halftime lead with Parker spearheading the way. As it was, the Steelers tried to get their ground game going against a poor rush defense and couldn't sustain drives that way. Mewelde Moore is a solid back that can make yards when he's got room. Willie Parker is a Pro Bowl back who can make yards out of nothing in a variety of ways.
