No its not that hard, because we have data and statistical analysis never lies, its just that majority of people dont understand and cant read stats and dont understand biology,physioloogy,math and how it all fits together. Here is the bottom line. Cheaters should get much higher punishments for testing positive because otherwise possible benefits outweigh the risk factor of getting caught.Also dopers like Anderson Silva or Jones are automatically excluded from any GOAT talk. Data proves their careers were cheats,there is nothing else to talk about.I think it's hard to compare an athlete that has gone from taking peds to his results in the immediate aftermath. The problem being that when an athlete comes off peds his body will struggle to recover and his test levels will be rock bottom now the synthetic test has gone. I wish there was a way of testing a totally clean athletes performance, have him juice, but test him a couple of years further down the line after he'd been clean a period of time, to see what long term benefits there may actually be. But then you have the issue of ageing to take into consideration.
