They probably are.
Given most of the coaches will come from Melbourne, and there are plenty of opportunities there, I suspect it is pretty rare for these candidates to want to up root their family to move to Sydney and take on a similar role that they already have or is likely to be available where they already are.
Just one of those things I guess.
I also think a head coach should have his team of coaches so if horse wants to blood every swan he can as a coach so be it, his arse on the line
