I can imagine the pressures in the sport, and by the coaches to be NUMBER ONE.
And, of course, the pressures from college and graduate school. Perhaps setbacks with one's thesis or dissertation.
Somehow there needs to be a better way to recognize people having issues and get them the counseling and support that they need.
I wonder if an autopsy is being done. There are notes of a concussion. But, an intracranial hemorrhage of one type or another is also a possible confounding factor.
