The father of five was obviously a key figure of family's past and had two of his sons (Giannis and Thanasis) play for the NBA.
Here's the statement by the Bucks:
"The Bucks family is heartbroken about the sudden death of Giannis' father, Charles. The entire organization, his teammates, and coaches are here to support Giannis and his family during this incredibly difficult time. Charles was a big part of the Bucks and will be terribly missed by us all. On behalf of ownership, we express our utmost condolences and offer our prayers to Giannis and his family."
Condolences to Giannis and his family during this difficult time, as they try to pull together during this difficult time.
