What else is new? Team USA will just dominate this again. Giannis with the Bucks can't win the championship in the NBA. And his team mates in Greece won't be better than the Bucks. Unless USA won't have their top 5 players on board. KD and Klay are injured. Curry won't probably play. Leonard, PG and Irving will be busy creating chemistry with their new teams. 
You think Popovich is that dumb not to pick good players? This roster of USA for this FIBA 2019 is massive and I know they can ball and penetrate in and out of the court. If there are team that can go head to head with them that's for sure Serbia again or perhaps Spain.Anyway, have you seen the exhibition game between USA and Australia? Australia have players that have something to prove to in the world cup, but this was a blowout game. 102-86 is the final score. Kemba helped the team to defeat Australia with 23 pts and 6 rebs.
Keeping an eye on Australia, I positively think that their team will remain capable of beating a good game. That's why their performance is a huge potential to achieve goals successfully. Maintaining their position, doing daily practices and many ways to enhance skills; great results will follow.
