Lining: "Facing the play"

[sir_eldren]

Hi,

I recently attended a hockey camp where I was instructed that it is a better mechanic to "face the play" when working the lines rather than keeping my butt against the boards. So I went on the ice in my evaluation game and tried just that. However, I was told after the game that I needed to face the play. *sigh*

Does anybody have any advice on how to face the play? Any things to key in on or be aware of?
