Here is a excerpt form the USFS document "2010 Olympic Winter Games Athlete Selection Procedure ".
To field the most competitive team, U.S. Figure Skating's ICMS will take into consideration results from the events outlined below to determine athletes who will have the most performance impact at the 2010 Winter Olympic Games. The ICMS, and the International Committee's approval process of the ICMS' recommendations, will take into consideration placement and competitive field at the following events in priority order:
a. 2010 U.S. Figure Skating Championships
b. 2009/10 ISU Senior Grand Prix Final
c. 2009 World Figure Skating Championships
d. 2009 Four Continents Figure Skating Championships
e. 2009 World Junior Figure Skating Championships
f. 2009/10 ISU Junior Grand Prix Final
So I think technically according to their published selection process, they could have picked Ashley.
Boy that would have created a firestorm!!
