I agree with you on Eichel.
But Gaudreau led the team in scoring and is still leading the tournament in goals . . . He didn't have a great game vs a stifling Finnish team (the whole team struggled), but at least he came to play this tournament. IMO he was the team's best player vs Germany, Sweden, Slovakia, and Russia and probably overall MVP. He's always played hard and produced when wearing the red white and blue.
WJC 7gp 7g 2a 9p +2
WC 16gp 8g 13a 21p +6
That's 23gp 15g 15a 30p +8 while representing the USA. If you include his World Cup experience, that jumps to 29gp 19g 20a 39p +12. I can't think of too many players with that sort of production, let alone American players. After a quick glance, it looks like Crosby, Panarin, Getzlaf, and Shipachyev are the only active NHL players who have played in at least 2 tournaments who have a higher career WC PPG average.
If he's not getting invited to international tournaments there's something wrong.
