I believe it's better to have a Defensive minded coach over an offense minded coach when it comes to goalies. I've seen both and it's pretty obvious the D coach can relate way more to the goalie.
might be true, if so I have not seen a defensive minded head coach in youth hockey. And even so, relating doesn't mean they can set up a practice so it benefits a goalie, nor can they coach goalie skills.
Don't get me wrong I am not upset about it, I just think it is a fact of hockey development.
