I really don't think that way as the other teams have better chemistry than the NBA. They only have few players to represent their country so they really know each other compared to the NBA where they are busy with the NBA season. A team that has a better chemistry will win, and we've see how other teams beat the USA in an exhibition match that says they are unbeatable.
Yes and no. Growing up in my hometown we had more HS players/larger pool to pull from than the small towns outside my city. I went to a good sports school but those small town teams had been playing together literally their entire lives. If they had some talented ballers it was hard to beat them and my school often lost to those teams with such chemistry. However top talent reigns supreme. A rival HS of mine, Lanphier, featured future Big 10 / Univ of Illinois player Richard McBride and a future NBA star player/Olympian/Finals MVP Andre Iquodala. Despite having the chemistry. they were absolutely no match for Lanphier. They ended up losing the in state finals game but it was vs a powerhouse (chicago westinghouse). Proof that elite talent most often tends to prevail.
Oh Durant is on a mission. Durant has felt underappreciated his whole career and I know the only reason he's playing on this team is because he knew he'd be the best player in the world to compete in the Olympics and he wants that glory. Will be fun to see him try and get that gold. Going to be hard to stop him and Lillard that's for sure.
But still USA will gonna dominate them with a perfect nba all-star roster.
Actually it's far from. Lebron, Harden, Curry, Thompson, Kawhi and others are all better than every player besides Lillard and Durant. This is actually a weak team compared to what it could be.
