I am curious, with 2nd generation players that have come through the NBA, Has there been a NBA player who is a father to another NBA player and both have won a NBA Title and a gold medal in the Olympics?
Disclaimer: Wikipedia lists cannot be considered the ultimate reference, although my limited research has shown no discrepancy in case of this record.
This Wikipedia list covers the second generation basketball players in the NBA, and mentions four father-son duos to have won the NBA Championship (in that order).
- Matt Guokas Sr. and Matt Guokas Jr.
- Rick Barry and Brent Barry
- Bill Walton and Luke Walton
- Mychal Thompson and Klay Thompson
Comparing that with the list of Olympic medalists in basketball shows only one of those eight players has won an Olympic medal (any Olympic medal), i.e Klay Thompson who won Olympic gold in Rio in 2016. So to answer your question, there are no father-son duos who are both NBA champions and Olympic gold medalists. Interestingly, had you posed this question four months earlier, there would have been no one from a father-son NBA champion duo to have claimed an Olympic medal.
