Pro Football Weekly says that new Steelers RB Rashard Mendenhall has been looking good so far in Steelers practices.  Below is the article about the impact Mendenhall is making:

“The way we hear it, Steelers rookie RB Rashard Mendenhall looks as though he will be a solid fit in Bruce Arians‘ offense. Mendenhall has caught the ball well in his brief Steelers career, and he’s also shown the speed that helped make him such a well-regarded prospect. Mendenhall and probable third-down back Mewelde Moore are likely to be the first backs off the bench for Pittsburgh, which will have a more versatile backfield than it did a season ago. Mendenhall, who is healthy again after suffering a hamstring injury early in May, will primarily play the role of keeping starter Willie Parker fresh. At the NFL Players Rookie Premiere, Mendenhall told PFW he can learn a lot from the productive Parker simply by “seeing how he works every day, just his attitude about everything. I learned that when I got there, and I just feel like I’m picking up a lot just being under him.”
