I'd be interested to hear from players with exactly 1 NBA title and 1 gold medal to hear which one matters more to them.
Me too but my off the cuff opinion probably says NBA Title. Not that the Olympics are easy or as often, but you're kind of supposed to win the Gold medal when you are USA since it is our sport and we have by far the best talent. Not to mention, the tournament is a fraction of your average NBA season.
Ask Patrick Ewing if he would trade in his 1992 Dream Team Gold Medal for an NBA Ring and he would stampede an orphanage to tell you his ring size.
