I won't give away too much but to put it simply, he does not want to play front row. Last year against Raiders (I think) he refused to come onto the field on the front row mid game. He said he had a back injury and sat out a couple months (remember?). That was all BS. He was not putting in at training, requesting to train with the blokes recovering from injury. All this because he just did not want to play front row.
Off season come around, nothing has changed. There may have been rumours earlier this year about him going Roosters? Not sure, but I have no idea where he may end up, I just know for a fact the club (Gus) want him gone.
