"who are the magical fiba experienced players from Australia ?"
Here's a good list:
Bogut - 3 Olympics, 2 World Cups, debuted in 04 Olympics
Mills - 3 Olympics, 2 World Cups, debuted in 07 Oceania Champs
Ingles - 3 Olympics, 3 World Cups, debuted in 08 Olympics
Dellavedova - 2 Olympics, 2 World Cups, debuted in 09 Oceania Champs
Baynes - 2 Olympics, 3 World Cups, debuted in 09 Oceania Champs
Broekhoff - 1 Olympics, 1 World Cup, debuted in 14 World Cup
Goulding - 1 Olympics, 2 World Cups, debuted in 14 World Cup
All these guys have played multiple tournaments and learned their teammates, their system and the international game. It's this experience and the consistency of the Boomers programs that allows them to utilise their talents and make the team to be a top 4 team in the world.
In contrast, the USA with more talent but less international experience and less consistency in the program, and a coach with less knowledge of the international game, finished 7th this year.
