Kimmage's comments often tell me only one thing, he is a petty, bitter and vindictive man.
If he listened to what people say rather than make his own agenda he'd have heard numerous anti-doping comments from Wiggins over the years.
No sport will ever be drug free but cycling has done a lot to clean up its act, PK just seems to ignore anything positive that is done. All the stats from the tour show they are riding much slower and climbing much less spectacularly than they used to when everyone was doped to the gills. He ignores this and just says "no-one's said anything to me the way I want to hear it".
He has had some good points in the past, the way he conducts himself does nothing to give and weight to any of his comments.
