The thesis of the article is that, once K started coaching the national team in 2005, he absorbed what he learned from Kobe, LBron and the ilk and changed his approach to hoops.
Here is one key paragraph, right near the end:
He says Team USA taught him so much: to consider his players’ motivations and wishes, to occasionally reveal his sense of humor, to delegate to his staff. Which is why Krzyzewski leans on his three assistant coaches — whose ages average 38 years — to make sure players fully understand his instructions. Krzyzewski still demonstrates the occasional drill, though his days of taking charges are over, and some of his older players can hardly believe the fearsome man they once played for now prefers positive reinforcement, studies his phone to fuel an obsession with weather patterns, secretly maintains Twitter and Instagram profiles — Krzyzewski’s most senior colleagues claim even they don’t know his handles — to monitor his program and the world in which it operates.
