I would be surprised to see Adam on the team... as far as the USA side goes, I was watching Freddy couples talk during the delay today and he said he is watching a couple players at the tournament this week.
Phil is on the team but has not commited to play. If Phil does not play and gives Freddy ample notice (I believe by the end of this week), Freddy can choose a new man. If he does let him know sooner than later (before the weeks end) the spot goes to the 11th man. So, depending on what Phil does, Freddy may get an extra choice or be given the 11th man.
I don't know who he will pick, he is obviously taking this very seriously, and will use his best judgement. Freddy also has Michael Jordan on his side as far as "assistants" go. That, to me, is pretty cool.
