SD I think the issue was that Jericho has been playing in the spot that Ricciuto will take - in the forward line. Yes, he can play those other positions you mention but he hasn't been ... so Craigy maybe sees it as a straight swap position for position.
Someone rang KG last night and wanted a tagger (Van Berlo, Doughty or Shirley) dropped instead but, as Cornesy said, Jericho hasn't been playing as a tagger.
I think he's unlucky too but he'll get another chance. If someone pulls out today he'll prob play.
