The sport has always struggled... During the peak Lance years it wasnt great... Thing is, you cant be a kid and race a bike without getting a beer bottle thrown at your head from a 6-wheel pickup! Cant do it!
Pro cycling will be full of dope as long as money is to be made... If there's no money then you'll get cleaner guys with no money to dope well and WADA with more money than the sport has.
Cycling was picked on because its "the little guy" in pro sports.
if WADA went after soccer, a HUGE money sport, or any other top sport they would end up at the bottom of the mediterranean with their ankles tied to cement blocks... Nuff said.
