I think that direct play, in general, is an American (and to a lesser extent, English) trait. We play soccer like we play other sports - try to score quickly, get the ball and try to score again.
The art of playing keep-away with the ball to allow your team to rest and recover (while tiring out the other side from chasing you ...), and get a foothold in a game is just a completely foreign concept to most US coaches. Our tactics are so naive.
Before you become a coach in this country, you shouldn't just be looking at videos of training drills; you need to watch a lot of Champions League soccer, to see how the game is played in many other countries, and get a sense of what's required tactically at the highest levels.
