If you want to play that way, you're going to need a generation of kids with the on-the-ball poise of Pulisic. Not necessarily the skill, but they need his anticipation, vision, and guile.
The other thing is ball skills. You need critical mass of players who can properly weigh and lead their passes. Bad passing forces the receiver to adjust to the ball and that gives world-class defenders too much time to recover. It's not too different than watching weak or inaccurate QBs trying to complete passes into tight coverage.
You also need players with good first touch. Watch MLS for a bit and keep an eye on how quickly players can gather a pass and make their first move. Now watch Barcelona or Real Madrid. A football analogy: it's the difference between a WR who catches naturally with their hands vs. with their body.
While our youth system is a mess (compared to other countries), through sheer mass of numbers, our national U14 player pool is more or less on level with the rest of the world.
The issue is that these kids aren't then put into professional environments like in other soccer-first nations.
Let's take a blue chip HS football player. There's a world of a difference between funneling him through Hawaii's program and Alabama's. The main ones being facilities, expectations, and competition (opponents and within the team itself).
It's the same problem with talented soccer players at the HS level.
