It was a fair and well phrased question.
Her response was also fair, even if it did not go into details.
Other media outlets are reporting on this LRC question by Rojo because 1)doping is a concern 2)they did not have the guts to ask it themselves.
Asking tough questions like this can be interpreted by some athletes as an accusation. Asking tough questions is not a good way to develop a chummy relationship with athletes. I value LRC because they do ask tough questions, and its not their job to get super friendly with every athlete and ask questions that get meaningless plastic answers.
The harsh reality of all sports today is that doping is a concern, and every top athlete should expect and welcome (if they are clean) questions about doping. Every athlete should think about and develop truthful and honest answers to the questions about doping that they know will be asked.
