The safest way to win an NBA championship is to land one of the league’s few unstoppable players. This is the superstar theory of basketball, and the Golden State Warriors and Cleveland Cavaliers are proof that it’s as powerful as ever. They’re in the NBA Finals this week because they happen to be the teams with Stephen Curry and LeBron James.

But even superstars require the right surrounding parts, and both the Warriors and Cavaliers have one player who isn’t an obvious reason for their run to the Finals—except to the few people who know why they are important.

They are the Australians. And every team in the NBA could use one.

It seems like a strange coincidence that Golden State center Andrew Bogut and Cleveland guard Matthew Dellavedova are Australians playing the same supporting roles in this year’s Finals that San Antonio Spurs forward Patty Mills mastered last season and Luc Longley pioneered on the championship Chicago Bulls teams of the 1990s.

But what if it isn’t?
