I find that worrying TBH... ... but that's cause I'm blue and white tonight....
It certainly strengthens the side and having Campbell playing in his more natural position of the halves will mean the Dogs will need to be on their A game, otherwise he might just give the boys a lesson... especially with Lewis beside him.
Walker is a solid competitor at fullback and considering his QLD Cup form, a real threat if he gets it right... this would only be for the benefit of the GC if it was to occur.
