This is all about the respect the riders have for thier jobs. Lets not forget its the hardest sport in the world and right now it's each riders cup final. Why are they risking it.

In my view, each team should get all riders on employment contracts that tie them into (if found positive) repaying all the team expense outlaid during their employment, for instance, if Valverde was caught, and say he's on a 3 year deal at £1.5m ( or euros), then he should pay atleast £4.5m back to the team..then add the Bike, Kit, Endorsements, Image deals etc... Massive pressure to stay clean. Take what Chelsea have just done to Mutu, and taken him for £9m, but put that into perspective, his offence was Cocaine, recreational drugs, not the real hard cheating going on here. (Gerolsteiner should do Schumacher also). This is all about the image of cycling not the egomania of an individual. Once a real world governing body establish, or if not, maybe the IOC, there should be a disrepute charge formed also for those sort of recreational blips, similar to football.
In the real world, if we were prosecuted for a drink drive offence, or worked on machinery, high on drugs; the likelihood is we'd lose our jobs when our employers found out. Surely simple things like this is a starting point not the soft, gentlemens agreements that the UCI think will work, get the teams to start playing hardball!

 Any other views of a constructive nature to solve this epidemic ?
