I'm not sure exactly where I've heard this but when I read into the situation with Carey Price and his goalie coach drama, some high level goalie coaches were trying to suggest to their goalies to adopt a Depth first/aggressive style because of how the shooters are now working on changing the angle of their shot on the fly (drag-pull wristers).
But that seems to have had a negative effect for goalies like Carey Price, whose new coach is now suggesting a squareness/angle first approach. Unless of course the situation calls for it.
