Cincinnati Bengals looking to add a RB

Bengals OC Jay Gruden called the RB position one of the team's top offseason priorities.  "With the running back situation the way it is we need to address it if there's a top of a line guy there," Gruden said. "What's exciting about the backs is I think there are a number of them that can come in here and help out a lot."  Cincinnati isn't expected to bring free-agent RB Cedric Benson back, and RB Bernard Scott can't handle a 300-carry season.  The Bengals could hit the free-agent market for a guy like Michael Bush, Peyton Hillis, or Mike Tolbert.  Or they could add a rookie with one of their two 1st-round picks.
