Now I finally have a source! Yay Canberra! Well, never yay Canberra but anyway.
I can't say for sure that the story is about Junior specifically, but this seems to have legs. Junior has allegedly been talking up BA to his team mates...
Now that he is experiencing Ricky Stuart coaching for a 2nd consecutive season, and not just the 1st year honeymoon period, Stuart's methods might be wearing thin... If he was coached by a potplant while he was at Parra, Junior would be talking that up too right now I reckon!
