No one knows WHY this occurred. It is too soon for even the doctors to know. The immediate concern is stabilizing Hamlin and saving his life, at least in the short term, meaning the next couple of hours. After that, the doctors need to figure it out. Is it a freak football injury? Is it something in Hamlin’s body that was unknown that was exacerbated by the hit? Or was it related to over exertion? Is there some substance involved?
It isn’t about assigning blame, or pushing an agenda. It is about the doctors quickly making a correct diagnosis, so they can quickly establish a more long term (tomorrow and afterwards) treatment to bring this young man back to health.
Hopefully, his family and the team doctors can help provide the information the hospital needs to help correctly diagnose the problem, and successfully treat him.
