It's hard to know without knowing what his budget was and whether any other stipulations were made on hires (such as being Australian). Mick Byrne is the only assistant he's had who could be remotely considered world class. Of course there's a reasonable chance that even with the right budget some of the right people wouldn't have wanted to work for Cheika. Rugby Australia needs to think long and hard about this issue though. We're clearly not going to have the budget to recruit whoever we want as head coach and then meet their hiring preferences for the assistants. We've got to work out what we need to spend to be competitive though.
