They put out a statement saying they aren't going to release him, but I read they're going to get him professional help. I wonder how bad his character has to be for them to take such measures? Seems pretty out there. But clearly there's something going on there. With talented players, it's smart to take all steps possible to get them on track before taking drastic action, just need to work things out & manage their personalities.
Munster has been in their first-grade set up for at least 4 years now, so they all know him pretty well & if Cameron Smith really is fed up with him after all this time, you'd have to think it's only a matter of time before things come to a boiling point.
