When trying to work out how, why or what went wrong with SB, you also need to factor in the unusual circumstances the influence of his Mother brings.
From what I have been told and can also see in reports when she is mentioned, she has (and probably quite rightly considering her unfortunate history) a huge distrust of authority.
As is well reported, his close relationship with her (as they should be) has, I feel, also give him an instinctive reaction of the line.. "don't tell me what to do".
It becomes very difficult for the Club's Management to control or even Mentor someone with an ingrained and deep seated distrust of this type and it has influenced the type of people who he has surrounded him with, to his detriment..
Hopefully the Club's development program has learned a lesson from it all.. and also let not ssume all our Juniors are going to act the same way.
