I wish I could like this more than once. I am so fed up with hearing about how "inept" ASADA was. They had a difficult job to do and faced legal challenges (and bullying) all the way.Just where was the AFL tribunal "scathing" of the ASADA investigation? If anything the tribunal praised ASADA for conducting an investigation in difficult circumstances, the AFL tribunal also highlighted a number of times on its lack of powers in compelling witnesses to attend and be cross examined. They also commented many times that ASADA explanation was possible in each of the examples you highlight, they just were not comfortably satisfied it was. They certainly did not dismiss ASADA's explanation of the evidence as implausible.
It may have found that the evidence did not meet the level of proof they required, but this is far from scathing.
The only real thing the AFL tribunal was scathing about was the EFCs poor goverance and lack of records.
