It certainly is hard to measure success, it all depends on what areas you are using as KPI's. Is Mornington in a better place than 2-3 years ago, hard to tell but I highly doubt their DOC is to blame. I would say that the high turn over rate in committee members over the past 2-3 years would have had more to do with the clubs success or lack thereof, all having their own ideas and views and directions every time someone new came on board would have made it hard for anyone to plan and build a program.
If you are looking at who is the leader on the Peninsula, it is very simple, Frankston, followed by Sth Pen, then a very distant Western Port or Mornington, then Chelsea in that order.
And hey, if he is getting $70k GOOD ON HIM!
