Yeah, I think Stewart has been really impressive at 12 and he's actually starting to look like what we hopped he would at 10, I'd not rule him out of another go at 10 if the opportunity presents itself, say if JOC (James O'Connor) get's head-knock or something and is out for the remainder of the game. I think he's worth a look, I wouldn't push him there, but he's looked good stepping into first recover. So I think he could still pan out as a flyhalf -- and he's got the toolkit to be a genuine World Class flyhalf, but he looks very good at 12 so don't fix what ain't broken.
I think the key to managing this much depth is to pick the bench for the game, keep picking your XV on form, and give guys the opportunity to work their way off the bench. I think we are more or less doing that, but someone like Hegarty I think will be vital for us if we make a finals run, and for next season. So we've just gotta keep him engaged get some club footy into him and bring him in for the games where we need him.
As for Berry, I think he's one of the best refs we have in Super Rugby, but he should never be put in the position where he has to ref a Reds game again. He use to play for them, I don't know how much more of a conflict is possible!
