I think it's reasonable to judge the coach on the game plan, which Dockeroo does.It's not personal, I just don't agree with anyone judging previous decisions using information that wasn't available when that decision was made. That's what hind sight is, an unfair judgement that people made mistakes in their decision making without accounting for their perspective at the time.
E.g. You don't know players have lost form till they've played a few bad games in a row. You don't know Young is going to play well as a mid till he's played well as a mid etc.
There is no value in hindsight. There is much value in not blaming, but being honest about what actually happened and learning from it.
Pretty reasonable comment regarding the lack of vision around the use of Young too. It isn't retrospect to look at the loss of some mature midfielders as well as the fundamental issues that come up with playing Brodie, O'Meara, Fyfe in the same midfield.
