Could have been Merrin, Wallace, or Peachey, or CHN, or Tim Browne. Probably was Hook though. So I guess RCG must have played the best footy of his career after Hook left, then?
I don't think he was talking about any one of those players though. Wallace and Browne were offered jobs at the club when they retired, which they wouldn't have got if they were considered cancerous.
Given the emotional speech from Gould about Peachey and CHN when he announced they were leaving, and the high praise he gave them as people and not just as players, its not the way you speak of players that are cancerous.
So that would only leave Merrin. Although his form was down in 2018 and not worthy of the salary he was earning, I don't think I have ever heard one bad word said about Merrin while he was at the panthers. The opposite in fact. Gould praised him for being a role model to the younger squad and his leadership skills, and even wanted him to be named captain of the NSW Blues.
So realistically, RCG could only be referring to Griffin. None of the players would of had the sort of negative impact that would need to be described in an interview as a cancer needing to be cut out.
