When the Bengals signed BenJarvus Green-Ellis in free agency, the biggest knock on the running back was his lack of explosiveness. That's not a criticism any longer. Over the last four games, Green-Ellis has had five rushes for at least 20 yards, which is tied for most in the NFL. Prior to that, he only had six such runs combined in his previous 62 games, according to ESPN Stats & Information.
