Doping

So a positive way of looking at this would be that he was caught due to stopping doping whilst at Sky, and that making his values look odd compared to previously, when he was on the sauce?

There was talk of JTL last year after a breakout 2012, people were suspicious because of the lack of the BP. I would say his anonymous season so far and now this is a strong indicator that he was blood doping last year and didn't this one.
