If the facts in this article are true Asbel Kiprop may get off with no ban at all. Everyone assumed he was guilty and that was it after his test came back positive but after reading the article there is a real chance he may have been clean at the time of testing. Seems odd for someone if he knew he was guilty to be so adamant that he didn't do anything wrong and stand by his story.
