Team USA Met New Zealand's Haka at the 2014 FIBA World Cup

Before a Group C game in Bilbao, American players appeared baffled as New Zealand opened with the traditional Maori challenge.

Before their Group C matchup at the 2014 FIBA Basketball World Cup in Bilbao, Spain, on September 2, 2014, New Zealand's players performed the Haka, a ceremonial dance with roots in Maori tradition that the country's national teams have long used to open competitions.

The display appeared to catch several American players off guard. Cameras showed Derrick Rose, Kenneth Faried, and James Harden looking visibly uneasy during the performance.

Mike Krzyzewski, then coaching the U.S. squad and known for thorough game preparation, seemingly had not briefed his roster on the custom.

Any unease had no bearing on the result. The United States controlled the contest and won 98-71 at Bizkaia Arena.
