It is also in the RP this morning. It would explain why we seem to want Carr back and have already signed Shields. To replace maybe Guy and Sam (if he doesn't get back to full fitness, and Dai has to make contingent plans regardless of wanting Sam back to full fitness, which we all do).
These guys always talk with Dai about the future, and some choose to move on. It is rugby. Much as a like Guy, who punches above his size and weight, it is for him to decide his own future and what he is worth. I have little doubt that it is rare for Dai to say to player, 'We don't need you any more, go find another club.' It is more likely, Dai says, 'This is what we can afford to keep you, please sign here.' And some players get a much bigger/better offer from another club, and sometimes they reluctantly move. Some stay any way.
