Should established champions help aspiring ones?

This week, the US Ski Team competed in its annual National Championships and while the yound and talented Shiffrin was there, some other top athletes were conspicuously absent: Vonn, Ligety and Mancuso, to just name a few.

Why is that? Can't the Alpine Team demand that its best skiers be represented to inspire and emulate the entire field of participants? If the problem isn't with the Stars chosing not to show up, it definitely is with their coaches and the Team not management.

I doubt this way of doing things would be acceptable with the Austrian Ski Team!
