Redskins plan for last Sunday was to rotate WRs Aldrick Robinson and Leonard Hankerson at X-WR every two plays. Hankerson played more in redzone.
Both are trying to take the place of Pierre Garcon, who we really only saw one half of quality football from this season. It's possible Garcon could be kept out for the rest of the season if his foot isn't improved by the time the Skins are off their bye this week. Neither Robinson nor Hankerson are great options going forward, but Hank's play in the redzone does give him a slight edge.
