Obviously, Logan will likely never see his vision of drugs free-for-all realized. In the meantime, one should be concerned with the message his comments sends to athletes. I mean, here you have the former head of a major national sport body suggesting that drug-testing in sport is pointless and intrusive, as though we were talking about ordinary people being hounded by their bosses over a little THC in their system from the night before. Without enforceable rule structures of some kind, there is literally no such thing as sport; sport, by definition, is about the overcoming of gratuitous obstacles existing in the very form of the game itself (e.g. sticks and only sticks can be used to put the puck in the net, and motorcycles can't be used in bike races). From a strictly utilitarian point of view, there are always more efficient and effective ways of securing the objective in a particular sport, whether it be getting from point A to point B before anyone else, or lifting a weight. But what makes sport sport is that the logic of maximum utility does not apply; sport is about rules that impose limits on the application of this kind of logic to the objective at hand, which itself often has no rational purpose.
If you remove the rules around drug-taking in sport you may still have a game in some form, but it will not be a game that tests the kinds of human qualities most fans and competitors are interested in testing. Instead of testing the ability of the competitor to master his/her genetic endowment and life circumstances, it will test his/her ability to get access to the latest and best drugs, and his/her willingness to take more and more extreme health risks in pursuit of victory.
Obviously, we're talking about ideal types here. There are drugs in sport today, and victory can sometimes be a matter of who has access to the best ones; and, a thoroughly drug- infested sport would still test some of the personal qualities that sport does today. It is question of how far we're willing to let things go in the direction of a drugs-driven sport. If we choose to let them go all the way in the drugs direction, we should not kid ourselves that we'll still have anything resembling sport as we have known it when it's all over. There's only so far you can go in removing the rules that constitute a sport without rendering it completely meaningless, or worse.
