Medical staff is all encompassing health – it is slightly different then “just” performance. Remember that your medical and health staff have to always put the health of these humans first. Their LARGEST responsibilities is to be AVAILABLE for any “strange” and health related issues.
As a professional, all you CAN do is to try to design, implement and then do the RIGHT actions when something bad happens – it can still happen, no matter to what degree. Have a plan, have some back up plans and follow protocols because player health is no joke.
Everything in football comes down to multi-disciplinary teams. No one is more important than the other and you need to have open communication and state simple facts without attaching yourself too much to it. This includes player availability – although health comes first, other professionals will have their say and decisions as well.
