Sky's only real crime was to naively set their standards too high at the start and not being omniscient when recruiting. I'm sure they'd do it like Garmin if they could start again. But they can't so some will criticise from their high horse even if they think they're clean. You're making them same mistake they made and being stupidly idealistic.
My issue is he's not changing his position. He knows Rogers has history, and I've got a shiny fiver says he knew about Barry. 10% of the riders on Sky in 2011 are mentioned in this whole mess.
As you say, Garmin got it right, but Sky continuing with the same position doesn't help them at all. For such a well financed team with people who do everything they're a walking PR disaster.
