Hmmm Petaia could definitely slip into 13 and JOC (James O'Connor) to 12. Who goes to wing when JOC (James O'Connor) comes off, Hodge is at 10 and a winger/15 comes off when we don't have a player who has been training in the back 3? Same scenario as you're proposing. Point is we significantly more cover for the centres than we do for the back 3 and we still put a specialist centre on the bench. Doesn't make a lot of sense to me.The flaw with that analysis is that I doubt that either JOC (James O'Connor) (James O'Connor) or Petaia have been training in the centres. Sure they can play there but JOCs brief will be to manage the game from 10, potentially for the whole 80, and Petaias brief will be to get through the game. I don’t think it’s odd under the circumstances.
