Really? 15 pages of comment and discussion of hurdling technique and "soft" events might suggest otherwise, but nice to see you concede the possibility the record was doped. So the debate is really about Coburn's bad manners in drawing that possibility to our attention.
When WADA estimates that up to 40% of professional athletes may be doping it would be reasonable to think that the discussion has moved from what is possible to what is probable.
