Whilst no one likes to see this kind of thing happen, lets have some perspective. Why is there so much consternation for a player who is not holding up his end of the bargain and playing like a Z-grader.
So it is beneath him to play below Premier League, because he had a few good games more than a year ago? It is not as if he didn't know that his perfomances where shiate, and that this was not potentially going to happen.
Hell, he even said that he expected to play in the Qld Cup next year, all Souths are doing is moving him there for the last two months of the season. I cannot see where it says we are sacking him, and why should a younger player be held back from playing Premier League.
I know guys who work away from their families all week, and only see them on weekends, and they do it all year round. On $350k a year, I am sure he can fly them up on Jetstar every weekend for two months, if he decides to play where he deserves.
lastly, go and put in that kind of performance in your workplace and see how long you would last. With the amount of crocidile tears on this thread, I would assume that your club would be happy to sign him up straight away on his present wages. If so, please let your CEO know that he is available.
