Haliburton was injured for a while too, which means that resting him isn't a bad choice neither, if he is back then he can get some minutes at times, to you know gain some momentum going into the season, but if he doesn't play much that's still fine. Plus this was just one game, we still don't know how it will go, maybe next game they will be the most played players, maybe they are rotating between games, we have no idea what they are planning.
People are making too big a deal over it honestly. The goal is to win games and ultimately gold. If th a t means playing some players over others than so be it. Seeing the game play out I think the right rotation was in. Durant was lights out, lebron was needed for his physicality, guards to spread the floor and defense from jrue. Next game someone else won't get playing time, no big deal. You need to keep a decent sized rotation you can't play everyone minimum playing time.
Some people creating issues towards in that situation and they make it look like that there's some issue happening. For sure those players understand that they have rotations to follow also strategy to be done that's why its expected that there will be some players will sit out on each games they play. There focus is not to have a good show but rather to take a gold medal in this tournament. People just creating drama since maybe they are enjoying seeing some issues online and spread hatred to couching staff who handle USA. Durant is excellent in that match also all of them really made outstanding contribution to get that win.
