It is terribly sad.
Oddly enough I read this article over the weekend about the suicide of University of Pennsylvania player Owen Thomas and the fact that his autopsy showed signs of chronic traumatic encephalopathy.
The cases sound so similar. Two likable, personable guys who's suicides left friends and family completely shocked and stunned.
