Disagree. He was one piece of the reason for their success, he wasn't "the" reason.Strongly disagree.
There was a sliding doors moment with Richmond for example with Dustin Martin.
If they'd pushed him out the door they don't have any of their 3 recent premierships.
The way they handle players is more the point there. We stuff up our best midfielders exit from the club and give up a potential top 3 pick - because he prefers powder to liquid AND got caught holding the bag.
Richmond changed who they were and what they stood for. They changed what mattered inside the club. Martin is a great example of what can happen if you get out of the way and stop stifling development with archaic structures and processes.
It was a bloody good decision to do everything to keep him though!!! It would have been much harder without him - I still think they would have been successful. But sure, having potentially the best finals player of all time in your squad doesn't hurt
