To'omua will be depth, he's a good player at either 10 or 12, but we have good options at 12 (Kerevi, Meakes, Hunt, Beale) and a first choice 10. His best chance at playing is if Cheika doesn't pick Cooper and To'omua acts as the utility inside backs reserve.
Yeah, whichever 10 is selected, I don't see either being a bench option so they become a dirt tracker for two minor games and a tackling bag holder waiting to be an injury replacement
