Here's my take:
Shiffrin is the future of the U.S. skiing and the sport. The weather delays have screwed with planning significantly. She backed out of DH as a result so that she can focus on Combined. She is a awesome - both in skill and the way she carries herself. She's a great ambassador. Anyone criticizing her right now has no idea what they're talking about.
Ligety is the greatest GS skier ever from our country and revolutionized the sport... but he's done. He said this was his last Olympics but it may very well have been his last ski race. He has a new son. He's just coming back off 2 years of injury. He's older. His heart just isn't in it the way it once was. I think he's done.
Vonn is a diva (not a compliment). While I respect her skiing results, I can't stand her; nor do most that are close to the sport that know/met her. My viewpoint long predates any of her pre-Olympic comments she made. Mine views are shaped by her self-absorbed personality (inflated self worth) which has grown increasingly nauseating over the past several years. She has some misplaced view that she is drop-dead gorgeous and some kind of irresistible sexpot. Nope. Not even a little. She's lost any appeal she once had but is so disconnected from reality that she can't recognize this. She is flat annoying; nails on a chalkboard. Her comment about not racing because she couldn't medal is not surprising and helps illustrate why I can't stand her. I'm sure there is a perfect word/description/term for her but it escapes me.
Team slalom event is a new event. Many are trying to figure it out. They're also in mid-season of the World Cup. So, with all the schedule changes, etc. I don't have a huge issue with it from that perspective. However, if the only reason you don't participate is because you might not medal, well, that's a pretty shitty viewpoint.
