First off, the espy's took place Wednesday night, the television coverage is on the 15th.  If you want to argue about that, google espy results to see for yourself that they have already happened.
Sarah won against Torah Bright (Snowboard), Layne Beachley (Surfer), Jamie Anderson (Snowboard), and Elissa Steamer (Skateboard).  Impressive that skiing held up against those sports in the eyes of big$$$$ ESPN.
It was the first time that an espy has ever gone to a skier.
Also, Kaya didn't ski last year, Grete got beaten by Sarah at the X-Games fair and square, Sarah also won the X-Games, WSI, Japan Open Slopestyle, etc. and landed a large cork 10 in the pipe in the superhit comp at WSI, so give the girl some props.
