In the last two years I think he has had two (?) games off the bench. In his second he was pretty good. You'll never be proven wrong unless he gets good time in the squad and on the field. Nobody can prove they can dominate at test level with half an hour's playing time.
As good as our locks have been this year, none of them have proven that they can dominate at test level. Why does Skelton have to prove he's this good before he plays? Would our current locks play as well as him in the Top League? They might get a few less cards, but I don't think they'd all command the status and dollars he does.
We are stuck with a policy that does not allow people to be selected if they play overseas (beyond three exceptions) because the Board is petrified that if it's open slather then everyone will migrate north. Either you toss out the policy, or you modify it, or you potentially don't select the best players for the Australian team. We might keep the Super comp viable if we don't select overseas players, but then again we might not make it any farther than the world cup round robin or the quarter finals. That will not help Australian Rugby viability either.
Injuries have killed our test campaign so far. Unless we give Rennie some leeway to choose the people he wants, we are not going to get the results we want and we will remain in the 6-10 category. We could easily lose five of the next six games. Where does that put us in the pecking order? Not top four, that's for sure.
With limited positions available from overseas, and then they have limited time in training with the team before games, you need to select players who can slot into the exact same game plan and not require further team and/or tactic changes. Koroibete, Kerevi, and even Quade pretty much do this.
I haven't been watching NH rugby but do take note of Skelton's reputation at face value. Certainly if they have managed to get him to potential then he should be a ruck, scrum and maul monster, let alone bashing hard yards in tight. But is he jumping?
He would probably slot in at 5, tight head side. 4 would need to be the line out guru - nothing strange there. Next I think we need three reliable jumpers, so 4, 6 and 8. In my mind this would either just fortunately align or the 6 role becomes more a hybrid lock/6 and we need 8 as a solid option.
I would imagine this is going to end up a different configuration without Skelton in SH tests than in the NH with him. And he doesn't get the time needed for the team tactics to adjust around him in general.
It's a nice problem to have, but the selection is not simply down to whether Skelton is theoretically good enough. It's a prime example of how having our players competing locally is a major benefit to the Wallabies.
