Injury management was a key issue in what transpired. It is important to remember that the medical staff have a medico-legal responsibility for the welfare of the patient (i.e. the player) which must come first. If things go pear-shaped due to medical mis-management then they are at risk of being sued - and this has indeed already happened. The cases of mis-managed head injury, and the long term consequences, that have been highlighted this year are examples - and there are others that have flown under the media radar.
Being a hot-shot sports scientist is all very well but there is an element of "all care and no responsibility" about it. My guess is that the medical staff decided that, on a risk-management level, they were not wiling to be a party to a situation where they felt the medical care and welfare of the players was being compromised. Remember that robust discussion, differences in opinion, etc.... are all a normal part of the medical process (particularly in a sporting club!). So, for them to feel that the situation was so unacceptable that they should depart (after so many years of loyal service) speaks volumes. Watch this space......
