Russia was also able to dope with few limits, and they were glowing brighter than Rudolph's nose. It's an interesting theory that Kenyan doping was so much more sophisticated than Russia's, particularly in light of a WADA funded report that found Kenyan doping was largely unsophisticated and opportunistic.
Russia was caught swapping urine samples in Sochi. I remember a lot of details about tamper proof bottles, and holes in the wall. Maybe I missed all the details, but did they do the same thing with blood samples?
