If they have been following this drug for a year before they made it part of the banned substance list then she had more than enough time to get herself off of this drug. In my opinion, if she is banned from playing then it should make sense she looks at retiring while she is still on top. Otherwise get on with it, allow the 1 year suspension, if that is what it will be and move on. The more they make a fuss over this, the more it will look circumspect just like doping issues Lance Armstrong faced.
