Two things after Round 2

[Lods]

A couple of those clubs have stuck with their coaches through a rough period and come out the other side.
If you're a successful club you won't go through coaches at a great rate.
If you're an unsuccessful club the changes will occur more often.

Are clubs successful because they stick with a coach or is it because they're successful they don't swing the changes so often?
It's a bit of a 'chicken and egg' argument.
