Thallen doesn't really count as a US original member. I don't think Ares can take him he might have been good in the past but from what I saw of him in single spar this year, he is not a great sparer. Not sure about David either, I don't think he will be able to spar as good as he used to either. Not that because him and ares are rusty, it's because of today's graal server performance. Even the ping for Americans is higher than it used to be.
Although Brett is great in single spar he isn't so good in gs because he doesn't care about it. I'm still in my word, US old team can't win a gst in today's era. You can't really count Thallen in US either
