It is a fair point. Its the idea that Froome is standing on the side of cycling's credibility (and the refference to Indurain as some sort of predecessor

) that is stupid.
But a doper winning could for once do the sport some good. Cycling has never had a "doper" win its main event. Its had plenty of dopers caught after they won, but a TDF edition loses 90% of its relevance once it is over.
Which makes it so easy for cycling to always, year after year, decade after decade, dismiss doping as something that happens in the past.
Having a "doper" win, may finally force cycling to accept the reality that problems aren't solved by closing the blinds and pretend they aren't happening.
