The thing in our favour with CHN is all the clubs chasing him are shithouse (like us). If the Roosters, Eels, Panthers or Storm were after him, then he might leave but the other teams, including the Raiders, are fringe top 8 sides (some might disagree but I'm not convinced the Raiders are a perennial top 4 side yet).
I think, or should I say hope, next year with a few smart recruitments and a new coach, we could be at the level of those other teams so it would be a sideways move for CHN. Better to stay here and be part of the rebuild
