14. Sean Rooks – 46 Years Old
Fans are still shocked at the untimely death of this 12-year NBA veteran who had retired from playing in 2004, but was in the prime of his coaching career with the Sixers when he collapsed and died in a Philadelphia restaurant on June 7, 2016. Rooks was passionate about helping young players and reportedly died just hours after interviewing with the Knicks for an assistant coaching job in New York. Cause of death is not yet known but our prayers are with his family.
