Interesting analysis.
We can see in cycling that it reached a point where you had to dope if you wanted to compete, and more than likely, that's the case in Athletics, etc.
With the latter sport, it's a more individual pursuit, with an AFL club, we're talking about 45 footballers, with almost that many in support staff.
So is it really possible to sustain a team-wide regime with no one ever finding out about it?
I'm doubtful.
Remember the Mafia never existed until the joe velachi testimony in 1963.
If it wasn't for the acc would you have found out about essendon? Rumours maybe but not much more.
