How did that work out for us? If you think the circumstances are the same and anyone thought what happened with McKenzie taking over was ideal then you seriously underestimate what it takes to coach a national team.
Deans was fired leaving the ARU with little option but to appoint one of the Super Rugby coaches. This time they are months out from a Super Rugby season.
This here is why I find posts like yours so bewildering. The ARU FIRED Deans, choosing to pay him out and then throw a new coach straight into the RC with no preparation. And no, it didn't work out great. Now, through its own awful and incompetent management of a minor crisis, the ARU have had a coach leave mid season, with the team about to hop on a plane, leaving them no option but to appoint a new coach asap.
I agree mate, it's far less than ideal and preferably you'd want someone to focus purely on the Wallabies. But guess what? The ARU have now manufactured two coaching vacuums at critical junctures in two years and their choices are thin on the ground.
They want Cheika? Well he'll consider it, but he has some conditions that include allowing him to coach the Tahs. He's on a hiding to nothing being thrown in like this, so he's well within his rights to put a few conditions on.
Don't like it? As I said, take it up with Bill and tell him to go chase Eddie Jones, Robbie Deans or Jake White.
I'm not underestimating the job mate, I'm just telling you your anger is directed in the wrong place.
