Aah, it's a terrible thing. The first casualty in war is always the innocent.
Actually, once they're in college they can still be eligible right? If not for Junior team then for the women's team? So maybe they can just skip their senior year of travel ball, since kids of this caliber already have full-ride deals in place, then play some college ball and be eligible for the national teams.
And let's face it, this affects hardly any players, if you're looking at the big picture. Of the hundreds of 18u teams, how many players have a realistic shot at this team? I guess a lot more different ones, now that all the PGF players aren't eligible, but still. Maybe a hundred, out of several thousand? And out of those hundred maybe 40 get invited to try out, and of those maybe 15-20 make the team. 99% of the players won't be affected at all, so that's a good thing! It almost makes this not newsworthy!
It's probably good for Canada, Australia, Japan, China, and all the other teams the U.S. usually beats up on, and should make the international game more competitive, which is also a good thing. Mercy rule games get boring after a while.
