But there is a very good reason why that didn't matter. Every drug cheat ever caught says "someone else gave me the stuff'. 100% responsibility for what goes in is the only way it can work. Did feel for the players though, but compared to others - even others in the AFL - they effectively got off scott free before
WADA stepped in, and the AFL oversaw that.
I think you'll find the AFL wanted it over well before then, it wasn't the AFL extending the process but rather other parties like ASADA/Essendon/Hird.
I'm pretty sure the AFL care a shit load more about the AFL brand and its value than they care about disgruntled bombers fans.
That's one way of looking at it. Another is, that the AFL after seeing the game dragged through the mud and its brand tarnished , may have thought "shit, we don't want to go through this again, there are a couple of other clubs with question marks over them, but lets just move on as quick as we can from this giant cluster****".
On the balance of things, Geelong are probably ok, because despite having clearly had a quasi relationship with Dank, both via Robinson and their drug purchases, they were smart enough to keep him at more of an arms length than the bombers did. However , Dank also had a habit of dealing with mystery substances, and Geelong never tested the stuff they got from him (and at the time probably had no reason to do so), so anything is possible. More of a concern is Geelong's complete denial of anything but the most trivial of connections, which tends to fuel speculation. Also, if Dank is supplying the gear for injection, is it really that important whether it is him or Geelong club doctors actually injecting it in terms of trusting what is going on, if the material wasn't tested?
