about the drugs in sport thing in general.
Ask yourself a few questions,
Why do professional sports exist?
If you think, they exist to entertain and to advertise, they are not about competition as such. Competition is only a means to an end.
Is doping a problem?
If the reason for pro sport is to entertain and no one cares then no. If the audience start to have a problem with doping then the sport has a problem and needs to clean up.
Look at cycling, the audience in SOME countries have an issue, i suspect that in some countries the entertainment value is all that matters.
Look at football, i may be convinced that doping is riff, but i suspect the average footy fan doesn't actually care. They watch it as entertainment. Look at WWC style wrestling, everyone believes it is fake but it is not really about sport but about entertainment.
