Renato. I respect your knowledge as a track and field coach however I am finding it increasingly hard though to respect your constant defense of East African athletes (mostly Kenyan) with respect to doping.
What do your facts here mean? Really? What did the fact that Russia annually caught a handful of athletes for doping really mean? - that Russia only had a handful of athletes doping each year? Turns out the entire national program and probably 9/10 athletes in the Russian national team were up to their eyeballs in drugs.
What you produce are facts but more so selective statistics that are nice but ultimately meaningless.
I do agree that systematic doping by the Kenyan federation is probably a bit out of reach - but certainly not down to moral justifications. The reality is Kenya is a country with easy access to drugs that enhance performance, drug testing protocols that are hardly state of the art to put it mildly and a National federation that whilst may not condone doping, pretty much operates on a hear-no-evil, see-no-evil, speak-no-evil basis when it comes to taking percentages of it's top athletes earnings (which we both know they do).
I doubt you seriously believe that doping is the problem of the "middle class" of athletes - yet my instinct is that you want yourself to believe that top talent simply "separates" itself and leads to desperation amongst the remainder who scramble around and dabble in the world of doping out of desperation to become one of the elite.
If you get to the point where you do believe this - then you, with respect to the realities of doping, are basically like the track and field following world up until a few months ago - completely ignorant and delusion to the realities of doping in this sport.
