Happily. Skelton going ok means he also contributes positively to the set piece as well as getting over the gain line every occasion he has the ball (as is claimed by many of his fans), hitting all rucks within spitting distance and effectively cleaning out every French player over the ball and disrupting every opposition maul (which I don't doubt he will do a good job at).
The other mystery selection imo was the omission of Jones from the bench in place of Hodgson to bring more size and aggression into what is a fairly unbalanced backrow. But that was on the assumption that Carter should have been on the bench. If he has a bump as apparently mentioned by Cheika, then Jones on the bench in place of Skelton.
Just to clarify, I believe the weakness of these selections in the set piece is the only area where the French could set up a win. If they do that, then I believe it is wholly attributable to poor selection in the forwards by the coach.
