I'm suprised Giannis signed for this. He plays tons of minutes in NBA and with immense effort at every spot of the court. That's nice. I'm not sure Greece will have this luxury for too long though. 24yo Giannis is still young, but further on I wouldn't bet on him as regular Greek NT member.
I got this idea today that the best for international teams is to have solid/good Eurolegue's players and NBA role players. Australia without Simmons, Canada without Murray, I'm not sure Jokic and specially Giannis will be regular members of their NTs. Good example of a bad example is I guess Slovenia. They had 2 studs, FIBA superstars in Dragic and Doncic, with both of them they could go against any team in the world, but without them they are not much. Or the same Latvia, with Porzingis and without him...Greece is leaning towards that direction as well. With time NBA stars will be pushed harder and harder to skip international tournaments.
