Explained below from VN article.
JTL is trying to say that in 2012 winning ToB and doing well at WC is "normal". He obviously submitted a defence that he was sick through 2013 and overtrained. And that the 2013 results are "abnormal" due to those factors.
Now who's to say 2013 is doped and 2012 not? Although that's a stretch.
The likely scenario is he doped through 2012. He broke his collarbone and Sky were ready to sign him along with Garmin come ToB time. He couldn't help himself and wanted to perform. He dropped a bag and dosed with EPO. He won the ToB then was picked as the lead rider for WCs due to Wiggins and Froome being DoA from the Tour & the Olympics.
What now? I'd say he topped up on more EPO and risked not winning and being tested. He rode well and was still with Nibali and Gilbert with 2.5km to go.
In defence or Sky and Garmin their testing was probably only a snapshot in time. If his doping had cleared his system then there's little they would find on that front. But they would know he's a chump talentwise and not hire him.
The other issue is BC and Sky are intrinsically linked. If JTL was partying like it was 1999 and attending Sky training camps and riding the Worlds with BC then Endura, Brailsford (Sky) and British Cycling all have something to answer for.
