I read an article around 4 yrs. ago where he said (if I am recalling it correctly) he had worked with “Olympic sprinters” but I never found any examples of who those people might be. This was either prior to or right after he had started working at UM so it would almost certainly have been someone who attended WVU. I definitely had/have my doubts about the claim. The article might be linked to one of the threads here on the subject-possibly this one(?).
