I agree AFL does not look like it would be simple for PEDs to be of help.
In weight lifting steroids seem to be a big advantage.
In cycling EPO is a clear advantage. It allows you to go on the edge day after day. Lance Armstrong was competitive but not really looking like a Grand Tour contender until he took EPO and crossed the line in first position a few times. EPO is also different in different people. Armstrong could take more EPO than some others and still stay below the limits tested for hemoglobin concentration. Yes he still had to be a great cyclist before he took the EPO but he could win with the best doping system in the trade.
