I find the implications in your post an issue, as they only serve to perpetuate the us vs. them dynamic. Firstly, the implication that because many believe doping is involved in the British rise to overachieving sports prominence, that they believe it is the only factor and therefore every single British success would be greeted with sneering and cries of doping. And secondly, the implication that because a particular section of British sport has not done that well, that aspect is therefore clean, and this therefore produces a case against other parts of British sport being dirty. Also, I would say that while some of the sneering and snarling done in the Clinic is counterproductive and sometimes, yes, bitter, there have also been a great number of posts that are either gloating or poking the bear, which has only served to perpetuate or catalyze the anti-British sentiment that many defenders of the British team decry. I also remember that you had to back down from your position five years ago where you were apoplectic about Cobo but took a lot of convincing to apply the same cynical eye to Chris Froome.
Doping on its own won't make you a worldbeater, certainly not unless you go full Mühlegg. What's to say the sprinters aren't doing exactly the same as the other athletes, whether clean or dirty, but due to differences in coaching style it's not clicked, or they have the wrong people in the wrong place, or they just don't have the talents to compete against the world's elite in that discipline, or for that reason more funding and attention has been paid to disciplines where they do? The British sprint teams having a down period doesn't necessarily make them any cleaner than the teams that are beating them, nor does it automatically make those who beat them dirty, and the British sprint team having a disappointing Olympics certainly doesn't say anything about the chances of fairness from athletes in completely different sports. It depends on what those various sporting authorities spent the funding money on.
