"The Redskins continued their apparent quest to sign running backs who once were productive. After signing Larry Johnson recently, Washington finally signed ex-Steeler Willie Parker on Friday.

If this were 2007 or so, then Washington would be in good shape. But, because this is not, the Redskins have a collection of question marks in their backfield. Parker and Johnson, along with Clinton Portis, all rank among the NFL's top 10 rushers since 2004. However, none of them are coming off a stellar season.

The question then becomes: Who will be the primary rusher this season? Parker apparently signed a one-year, $3.5 million contract, according to ESPN's Adam Schefter. Johnson has a three-year deal, but reportedly would only cost $150,000 if he were cut. Portis, meanwhile, would be owed $6.4 million if he is cut. Don't forget, Portis is coming off a season in which he missed eight games with a concussion.

Parker, 29, rushed for 389 yards this past season and, if healthy, could give Washington more of the explosiveness it has lacked in recent years. Then again, he only rushed for 4.0 yards per carry this past season and has not rushed for more than 4.4 yards per carry since 2006. He also hasn't had a run longer than 34 yards since that season. The Steelers did not exactly have a great line the past two years, but they did win a Super Bowl.

The National Football Post reported that Cal's Jahvid Best will visit the Redskins, but that was posted before the Parker signing. Apparently, his visit may have been cancelled, according to 106.7 The Fan. Best would be a candidate for their second-round pick and would be the sort of addition they need: a young, explosive runner. Best also can return kicks."
