I'm not entirely sure what your question is. Regarding the U.S. cycling team in 1984, the blood-doping program was a sleazy little enterprise conducted in secret by U.S. Cycling officials, employees, or contractors. Although the type of blood doping administered to various members of the U.S. Olympic cycling team may not have been expressly banned under then-current doping rules, U.S. governing bodies had been quite outspoken in their condemnation of the practice, so it was a huge embarrassment when it was revealed, after the '84 Games, that members of the very successful U.S. Olympic cycling team, with the assistance of individuals paid by U.S. Cycling, had been secretly engaging in the very practice that U.S. officials had been publicly condemning. It was, in fact, U.S. Cycling's embarrassment about the revelations over its doping practices at the '84 Games that quickly led to the promulgation of rules banning the practice, with the self-righteous folks at U.S. Cycling leading the way.
But U.S. Cycling's sleazy but not necessarily prohibited blood-doping program was obviously quite different from the nonpunitive drug-testing program conducted by USOC and TAC. Although officials may have sought to rationalize the program by claiming that they were simply trying to figure out the extent of banned doping practices among top U.S. athletes, it seems much more plausible that they were primarily concerned with avoiding positive tests for banned substances from U.S. athletes at the '84 Games.
In any event, I still hope to hear about the evidence backing up Lisa's assertion about Julie Brown -- not because I doubt Lisa's veracity, but because I want some details to confirm long-held suspicions. (To me, if a top athlete chose to work closely with someone like Debus or Charlie Francis for a number of years back in those days, there is something like a rebuttable presumption of doping. Athletes of good character can find coaches of good character.)
