Ok, I think it's alright for a past champion to comment on someone or some organization that that champion has problems with. I read the comment as fair treatment for all champions that may have some skeletons in their closets.
That being said I also believe that everyone in pro cycling at that level dope(d)(s). Much the same as power hitters in MLB, and just about everyone in NFL. If that's the case they are already on a level playing field...
All the same, I don't like doping as it doesn't really test the rider. Instead, it tests their sports physician, and pharmacist. I'd rather it were a clean playing field as that, in my opinion, would more equally test their talent and willingness to endure pain.
Just sayin'
