If this story comes as a surprise to anyone, then they have been naive in the extreme.
However, it is the long-term damage to sport that makes me most sad.
Be it doping or match fixing or whatever, it means that the ‘shock result’ is now always liable to be questioned. No fairy-tales allowed any more I’m afraid.
No minnow nation is ever going to beat Pakistan at cricket without it being called into question.
No cyclist is ever going to dance up a steep climb and smash the rest of the field without eyebrows being raised.
Life bans are the only way.
BTW I don’t think Bolt is a doper. If you look at his natural attributes (long levers, a glut of fast-twitch muscle fibres and the co-ordination to harness them) then I think we can still have some faith. But in the nasty world of cheats and sly innuendo, there will always be room for doubt.
