What is different about this group of national team players is how young they are.
McKennie and Pulisic are still 19. Tim Weah, who has already scored two goals in three official games for Paris St. Germain, and Josh Sargent, who has started out at Werder Bremen's Regionalliga team but should get a shot on the first team, are just 18.
Ten or 20 years ago, the top Americans in Europe were mostly seasoned pros who began their careers in MLS (Brian McBride, Clint Dempsey or DaMarcus Beasley) or college stars (Claudio Reyna or Kasey Keller).
The current generation consists mostly of players who went straight to Europe out of high school if they weren't already living there. Just two the 19 European-based players Dave Sarachan used in 2018 ever played college soccer: DeAndre Yedlin (two years at Akron) and Eric Lichaj (one year at North Carolina),
Twelve headed to Europe almost as soon as they were eligible to make the move, at the age of 18 for most, and four were raised there. Of the remaining three players, Matt Miazga and Yedlin moved from MLS clubs for transfer fees while Erik Palmer-Brown left Sporting Kansas City after last season as a free agent.
We are already seeing the pipeline of American talent expand as European clubs hook up with agents and take advantage of the talent being produced by MLS academies.
But it will always be a numbers game with only a fraction of the prospects ever making it.
Some like Rubio Rubin and Russell Canouse have come and gone, leaving Europe in the last year from clubs in Liga MX and MLS, respectively. Rubin, now at Tijuana, is back in the national team picture. Canouse could be soon, given his play in recent weeks for D.C. United.
For every Pulisic at Dortmund there's a Junior Flores, who never made the first team, or for every McKennie at Schalke 04 there's Haji Wright, who dressed once two seasons ago and may never get another chance.
