One thing I've noticed about recent American men playing the game is they're bulkier than most others. Seems like they've sold out on having a power game, which perhaps gets you to the top of the heap here, but their court coverage and shot-making skills are severely lacking. Kind of reminds of our soccer development in the generation that missed the World Cup. We prioritized kids who thrived in a brutalist, physical game and shunned the ones trying to work the ball. Just a guess, but maybe the kids with the higher ceiling is getting drummed out of the game at an early age by the kids who can batter the ball. Then we're left with one-dimensional players.
