Well if you look back at Ryder's career, there's actually a lot of evidence that he's clean. If you do the math on his power outputs during this year's Giro, there's more evidence there.
No one but him knows for sure, of course, but I feel comfortable being a Ryder Hesjedal fan.
There is, however, a slightly worrying paragraph in Barry's affidavit referencing a 'pro mountain biker' training partner. Hesjedal was a pro roadie by that time, but it was his first year and of course he was a mountain biker before then. They're both Canadian, both on the same team. It makes sense for them to train together. The name is blacked out, so I guess we'll see if it all comes out...and really this is very thin, and I have to think that his time on USPS would have been more successful had he been willing to 'partake'. He obviously has the physiology to be a GT rider, after all.
