I wouldn't call Jokić an old school center because he does the thing old school centers did, but also much more than that. We never saw a player at that position with those kind of passes and court vision who can also start a fastbreak of rebound, push the ball and also play on the low post to score when his team need it. I mean he can play on low post, on high post, he can shoot, he can pass, his conditioning has gotten to a point where he can play regularly 40+mins. He's not top notch defender but he's big and has quick hands. My point being Jokićs won't grow on threes in the future but the game has involved in some sort of positionless basketball and I agree with the notion of few inches taller Larry Birds dominating. Look no further than Wembenyama who's going to be the next big thing for the NBA.
Also, while I'm at it, this USA team for World Cup has a lucky draw because Canada and Brazil are in the same part of the bracket essentialy so it will be next to impossible to both those team reach QF. Without that luck USA would be in serious jeopardy of missing the Olympics. But it's not like they care.
