I think his career, as he knows it in basketball, is over.
Probably so...
A very similar incident happened to a guy I went to HS with, a few years back...
Guy hit him,he got knocked down and hit his head on the curb. He was found dead a couple days later at his home. Coroner ruled blunt force trama to the head as the result of his passing. Guy was originally charged with aggravated assault, and then involuntary manslaughter. He eventually plead guilty almost 2 years later to the manslaughter charge. Sentencing was 5 years,suspended to 3 years probation. I foresee about the same thing in this unfortunate circumstance.
Then, it will be a civil matter where the deceased family will sue for wrongful death, and win...
Terrible situation as a whole for everyone.
