Just about the only pending topic not asked of Mike Shananhan following Sunday's rookie camp practice involved the running back situation. Granted, both the Redskins head coach and Tim Hightower expressed a mutual interest in having the free agent back for the 2012 campaign. Should the team and veteranrunner agree to terms, the backfield would largely be set along with second-year runners Roy Helu and Evan Royster.Then again, the draft has now and come gone and Hightower, who is recoveringfrom a season-ending knee injury suffered last October,remains on the open market. Plenty of time exists between now and the start of training camp - thoughOTA's start this month - so there might not be a calendar issue for the Redskins. Two running backsdrafted in the later rounds of the just completed NFL draft add depth, butthe need for aninside runner remains.However, should another team make Touchdown Timmy an offer he can't refuse - or the recovery period moves slower than expected or the missing cap space stays missing - then what? This recent article on NFL.com ranks Hightower as the top free agent RB on the market, but that distinction is hardly carries an asterisk considering the motley crew. The top-five list also could use a scrubbingsince one listed option signed elsewhere, another one is on the verge of doing the same, another is talking retirement and the remaining two are Cedric "rap sheet" Benson and Thomas "3.1 ypc" Jones.Why Hightower and the Redskins have yet to put pen to paper, unclear. What is incredibly obvious is that the other options are hardly interesting, but some veteran will be added. Considering Shanahan stated rookie Robert Griffin III is his starting quarterback, it would be nice for a more concrete ground game outlook.
