More than once might be twice, it might be 100 times. Damian Barrett has given no more information than it happened more than once, and he is doing what any journo would and is allowing ill-informed viewers/readers draw their own conclusions and make their own assumptions about what happened (which you have been too happy to make ill-informed assumptions in your above post), which of course is intended to keep the story bubbling along.
What is certain is that one of our on-field leaders offered support to young Joel as soon as the siren sounded - that is about as swift a response to the issue as is humanly possible. Did you want our leaders to renounce Sherman and stage a sit down protest while the game was still on? How you can possibly draw conclusions that our club was slow to move and lacked leadership in relation to this issue defies logic. It has already been resolved to the satisfaction of the aggrieved party less than 2 days after the match, with our club having been in constant contact with GC, the player and the AFL in the interim to ensure that the player and his club were given a satisfactory resolution to the issue. Sometimes no matter what our club's actions, some people will find fault.
It is a shocking situation handled as sympathetically and as quickly as could possibly be handled by our on-field and off-field leaders.
