I think people might be reading too much into this. If as PG mentioned, Codling does have health issues, maybe he does not want it out there for everyone to know, maybe he his happy to slide away quietly. Maybe he was just brought in for a short period, do his thing and then go. Maybe we wanted someone else who was not available until after the WC so he stepped in to fill the void till then. Does not have to be cloak and dagger stuff. Coaches come and go. Maybe he has had an offer he cant refuse. No reason to thing there has been a big falling out etc. As said earlier, he never really hangs around anywhere for a great deal of time.
