From what I have been told by multiple sources that were in attendance at camp, was that Stranges was just ok, and not nearly close to being a top player at camp. "Other than the 10-2 skating all over the place, you wouldn't have noticed him at all" is how one scout described it to me.
I agree with the above "Want to avoid being snubbed? Go out and dominate and make them put you on the team."
With what has transpired in the past with Stranges and USA Hockey, I believe he needed to be so good that he forced his way on the team, and he didn't do that by many accounts. Past reputation only gets you so far, especially if they are looking for a reason to cut you. Being mediocre in the camp and being outplayed by many players including others that were cut, is not a way to demand being on the team.
