I see a lot of speculation here about the depth chart now with DJax on the roster but no mention of Special Teams. Typically, the 4th and 5th guys on the WR depth chart play Special Teams. On many teams so to does the #3 man. Neither Moss or Hankerson are ST guys. I have no clue about Roberts. If Jackson isn't going to return punts, then he is out of Teams as well.
I just don't see the coaching staff keeping 5 WRs with none of them playing on coverage or return teams. This by itself could spell the end of Hankerson and Moss both, unless Moss can beat Roberts out clean for the slot position.
