Chip & Chase, those were my thoughts as well. I think that Monas can also be included in that. He is obviously more serious but as a single guy I think he is fairly involved with the off field team activities.
As far as I am aware Willo is not gone for sure yet. It wouldn't surprise me if they manage to keep him on a cheaper contract even if his role was more as a back up.
Hicks, Monas and Willo leaving would definitely have some kind of an impact on the tightness of the group which has underpinned our move forward this season.
