This is not how USA Basketball expected to open its Olympic summer.

Nigeria probably didn’t expect it, either.

If there was any expectation of invincibility for the Americans heading into the Tokyo Olympics, it’s already gone — after Nigeria beat the U.S. 90-87 on Saturday night, an international shocker pulled off by a roster primarily filled by little-known NBA players that found a way to beat a group of All-NBA, All-Star and max-contract performers.

“We just wanted to compete,” said Nigeria’s Gabe Nnamdi, who goes by Gabe Vincent when playing for the Miami Heat. “We know what USA Basketball means around the world and what they’ve stood for for so long.”

The U.S. had lost 11 games before Saturday in major international play — Olympics and World Cups, mostly — since NBA players began filling the American rosters with the first Dream Team in 1992. None of those losses came against a team from Africa.
