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. 
This is the list of the team USA Roster.
Harrison Barnes
Jaylen Brown
Joe Harris
Kyle Kuzma
Brook Lopez
Khris Middleton
Donovan Mitchell
Mason Plumlee
Marcus Smart
Jayson Tatum
Myles Turner
Kemba Walker
That's a good line up, maybe not a star level of Lebron, Harden, or Westbrook, but these players can ball, they are young and hungry to win their first championship in FIBA.
