Let sports police themselves as best they can. Either enjoy the sport for what it's worth and suspend your disbelief until such time as expert judges decree otherwise, or find a different way of wasting your presumably valuable spare time. To do otherwise would seem to only add unnecessary stress to life.
Largely, yes, but with the added provisos that:
a) Sport cannot police itself effectively because it doesn't want to.
b) Ineffectively policed sport is not sport, unless the sport is dope test evasion.
WRT The Pog, I think it is natural, given the entire history of cycling, that a performance far out of the norm raises eyebrows. This isn't a sportive open to all, it is a rarefied group of the elite of the elite.
I quite like a dope fuelled rampage up a mountain. It is often far more exciting that clean sports. I just don't want the team to then tell me it is attributable to having better nutrition, equipment, or training than other teams, when those same things are available to all, or at least most.
In that respect, I quite like Pog, and as long as he doesn't come up with Brailsford style bullshit more power to him.
