Sure he wasn't just talking about his role and DeKeyser's role as a blueline tandem? That would make sense.
That's exactly what he was describing.
I just see it translating to a team-wide philosophy.
Nobody wants to take a risk/shot/chance in fear of being "that guy" that cost his team a goal.
Don't get me wrong... defence comes before anything and everything.
I just don't like when people develop a habit of making decisions based on of fear of screwing up.
