I don't think any Executive or Committee Member of a club is hiding behind a boardroom door at this level. These are the same people who do most of the off-field grunt work every Saturday plus a hell of alot during the week that allows the coaches and players to concentrate on their role. They see first-hand the dynamic between players and coaches, are not invisible to players and supporters, and are hardly making decisions of this nature without a pretty good understanding of the situation.
I personally can't see the merit in removing a coach mid-season unless there has been a significant incident worthy of immediate action but Glenunga and PNU have made their decisions and will move on. One or both of them will still be in Division 1 next season and maybe this period with an interim coach prior to appointing their next coach will turn out to be a positive.
