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.
