Thread is about coaching appointment gambles, it shouldn't mean that no one other than the OP can nominate coaching appointments to scrutinise.
They can, and do, but this thread is specifically about the big 4 so it makes little sense to include other teams that don't qualify.
I think the next part of your post sums up why the OP only wanted to discuss the big 4:
The reality is that if one of the big 4 **** up a coaching appointment, it will mean on field pain with minimal off field problems.
If North **** up badly enough, it could be the end.
