This is always an inherent risk of having such close (and sometimes muddled) ties between Sky Professional Cycling Team and British Cycling the organisation. I see no reason at the present time to suggest that Geert Leinders was involved in anything to do with British Cycling, but because of the connection to Brailsford and his very visible position as the go-to guy for both the national and the commercial interest teams, that Sky also support much of the track team and that several of the names are involved in both sides, either on road or track, the tendrils go deep into many places, and as a result one positive could easily result in far heavier implications. If Leinders was doping people at Sky, it's unlikely that it would have been the entire squad and even less likely that it would have extended beyond into the track guys and girls. But if it did come out that it was the case and Brailsford head was on the guillotine, he razes the ground for everybody because if he was found to be corrupt it would affect everybody in his care, which would be both Sky and British Cycling, and pretty much all of them.
The errors of judgment or whatever on Barry or Rogers, or Yates for that matter, can be spun away, isolated riders. They can go rogue, they can lie, whatever. What they do has little effect on what their teammates do in the public eye, and they can easily be explained away. To the point where Leinders' presence was revealed, they could have done this with a rider on the team, as long as it wasn't Wiggins himself or Froome, say. However, a doctor theoretically affects everybody on the team, and because Leinders' history is becoming evident and is blowing up in Belgium at an inopportune time (when the general public is more aware of doping in cycling thanks to the Armstrong case) it means now, if a Sky rider was to test positive, people could join the dots to Leinders and extrapolate it to the whole team, even if the rider had 'gone rogue'. Worse, if parts of the media and public don't know where Sky ends and British Cycling begins, it calls into question people that may never have seen, met or heard of Leinders.
I'm afraid that's part of the risks of the quasi-national organisational structure where Brailsford and several of his staff retain their positions in the national organ at the same time as working for a trade team. Especially as the sponsor of that trade team also sponsors the national team, further blurring the distinction in the public's mind.
