Both the UCI and USA Cycling made sure he never tested positive.
Other riders had to dope in fear of being tested positive. What happened when a good cyclist left USPS? They tested positive.
The other thing we know is the performance effects of EPO vary for complex reasons. For whatever reason, like Rasmussen, and Pantani at least, they find a killer combination of PEDs and it turns them into super heroes. Others aren't so lucky.
Valid while totally unproven assumption.
Riis and Armstrong both had Giro/Tour stage wins prior to taking EPO (latter actually competing against EPO users), so it isn't necessarily true that "killer combination" made them good. And as I understand it, Riis was mostly a support rider with very little own career interests until mid 1990s.
Aside from that, there is no evidence that any positive doping US Postal doping test was covered up. As many doping/health check tests (Hct/OffScore/EPO) were based on thresholds, it was also customary for UCI to warn any athletes who were close to these limits at least roughly in period 2000-2005.
To the claim that many famous cyclists tested positive after leaving US Postal, only Hamilton and Landis come to mind. There could be another factor than corruption for this. CIRC-report claims that Michele Ferrari was very conservative in his approach to doping whereas Dr. Fuentes was very aggressive with a wide range of products (while Landis apparently not his client). Another link connecting the two riders was team Phonak, which had many other doping problems, particularly in 2004 (Pérez, Camenzind).
