There is also more to running. If you make choices that lead to a dark cloud hanging over your head, it does not matter how fast you run. The US public is not as forgiving on this subject. You might be able to get away with it, but it always comes back. You just hope this type of scandal does not negatively influence the decisions of other athletes and compel them to take the same apparent shortcuts. Think of it like an Aesop fable.
