I think its pretty evident that international talent has gotten good enough that the USA can be beaten when they don't bring their A list. They really only do that for the Olympics.
A-List? this wasn't even the B-List. Heck there were guys that may not be even on the C team on this roster. A guy like Edwards may make the 2nd team, but he is a rarity on this team.
Who is on the US A-list in your opinion then, I'm really curios? I believe that it's not the player they send, but different style of play, coaching and also a bit of arrogance.
It would probably be something like this on the A-Team
Guards - Curry, Booker, Lillard, Mitchell, Morant
Wings - Durant, Tatum, Lebron, Butler
Bigs - Davis, Randle, Bam
So that is 12
2nd 12
Guards - Fox, Young, Harden, Edwards, Garland
Wings - Brown, Kawhi, George, Ingram
Bigs - Zion, Towns, Jackson
So I have Edwards on the 2nd team and because of a lack of American bigs, also have Jackson.
Now the 3rd team I'd have a lot of the team with guys like Haliburton, Bridges, Brunson, etc., but I'd also have some veterans like Brook and Jrue from the Bucks, Paul, and I'd have gone with Mobley over Banchero. I'd have Beal, DeRozan, LaMelo as well.
