I personly question the idea of a winger as the captain.. to far from the action IMO. Ive never been a fan of halves as captains because I believe they are natural leaders in the structure of a team both in offence and defence and have enough responsibility then to have to think about captain stuff, esp for young halves.
If I would say Mannah, Hayne and Smith are the only sensible options. If it was passed on to benny he could do it from 2011 but if its to be Hayne or Mannah they need some more exposure and to be in the starting line up in Mannah case who would still have Fui and Poore ahead of him, in which case Hindy should have it for 2 years before one of these guys can take over.
