US Winter Olympic athletes; really great or the others just suck?

Is the talent of the US Olympic athletes this Olympics really that great of is the usual Winter Olympics skiing powerhouses the Swiss, Dutch, Austrians, and Norwegians really suck this time around? In events like down hill, luge, Super G etc where you’d think they would do great they look like college students who snuck in. They are not that quick if they can even stay on their skis. Snowboard and snowboard cross sports I believe were conceived here in the states US athletes pretty much still own the keys to the mansion. What happened to the Dutch, Swedes, etc?
