Because NOP is currently under investigation by USADA and there have been multiple whistleblowers. That's why Jenny can be good and Rowbury=bad. That's why Shalane can be celebrated but other NOPers have to be handled with suspicion. I don't understand the level of denial on this message board about NOP. There have been allegations made from Kara, Adam, Magness, even Stuart Eagon.
The USADA report has damning evidence from Ritzenhein, Tara Welling and others. There are emails confirming Salazar gave persription drugs to an athlete which by the way is not legal in the regular world. Find me where Jenny or Shalane or Emma have been accused of these things. Desi too.
