For one, anything pre USADA is a completely different standard of testing than what we have now, and those of us in the wise know that are still probably a lot of people getting away with it now. Post USADA UFC testing was an absolute joke. TRT juicing was actually legal for a long period of time as well. Pride encouraged PED's ffs. How are we going to compare a bunch of different era's with different testing standards and just disqualify those getting popped by USADA now? I let ring accomplishments speak for themselves and Jones/Fedor/GSP/Anderson are all frontrunners. Testing be damned.
