In addition to having a 3-point line that's over a foot and a half closer than the NBA's, FIBA doesn't enforce the "above the cylinder" basket interference rule. And thank goodness, because this rule change led to Grizzlies big man Bruno Caboclo sealing his country's win over Giannis Antetokounmpo and Greece by doing something you'd absolutely never see in the NBA.
FIBA's allowance of goaltending is a game-changer, especially for NBA-caliber athletes. Players don't have to wait until the ball is no longer above the rim to tip it back in on offense, or swat the airborne shot away on defense.
However, the rule doesn't ensure dominance by NBA players, after Team USA -- the only World Cup team whose roster is entirely comprised of NBA talent -- barely made it out alive against Turkey.
Along with Caboclo, Brazil has current and former NBA players in Cristiano Felicio, Leandro Barbosa, Marcelo Huertas and Anderson Varejao, who put up 22 points in the win against Greece.
A dominant USA run doesn't seem to be in the cards this year, and with plenty of other NBA talent involved, including a Serbian team led by Nikola Jokic and Bogdan Bogdanovic, the USA men's national basketball team is under immense pressure to figure things out.
Maybe they can master this whole "goaltending" thing.
