He is going to play for St George, or he is going to play for Tigers. He is not going to be in any trouble. He has just had a week in Vegas and has two clubs fighting for him. He is fine.
Don't kid yourself Motlzen and his manager are not in trouble- if they mislead Saints and signed a contract knowing that he hadn't been given a verbal release they are in trouble, if not players could sign 2 or 3 contracts with different clubs and then say well I changed my mind.
As for 'everyone' leaving Saints - please is that all you've got. Players leave clubs all the time because of a little thing called the salary cap(see Melbourne). So now we turn it from a disagreement over a player to Saints are a mess, no-one wants to play for them bullshit. To be honest if this is how Moltzen conducts himself you can have him.
