I'm fairly sure you will find that any Essendon supporter will tell you Jobe is not a liar, the 2 Collingwood players are, Dank is, but not JobeRiddle me this.
If Dank didn't know TB4 was banned in his interview with McKenzie a year after he supposedly discussed good and bad Thymosin with Jobe, what bad Thymosin did he tell Jobe about?
When you add 2 and 2 together i'm sure you will understand why ASADA felt Jobe's evidence should be inadmissible. Mind you, that's only one example I can think of, ASADA may have other reasons as well...
