I think his problem is 50% laziness and 50% ego, when he was at the Broncs he was still improving, I think then he got hyped up too much in the Qld media as this giant with freakish ball skills. Started well at the Rabbits, but after being picked for Origin he really seemed to noticeably put in less effort, I guess he figured he'd made it to the elite and no longer needed to try. He probably think he can just coast along at the Titans for a few years, living off his rep and playing the occasional decent game when he can be bothered.
