Well Nathaniel is quite lucky to have played his career so far with one of the best in the league. Base Pack is an elite goal tender and doesn't need a lot of babying to get his best. Still, there are certain routines, and a special communication between defensemen and their goalie. For example, heading out to the ice, Pack gets a firm slash on his left pad, followed by right. Fist bump on his catcher, followed by a firm pat on the butt. You know, men things that men do.
On the ice there is a lot of communication between the two to the point they have even developed code words. Whoever is playing the puck needs to know where to go, so the one who can see needs to let the other know. There are a few tricks that Barca has picked up over the years such as looking for reflection on glass, but nothing beats a well placed puck set up for a quick pass and the moment you pick it up the goalie lets you know where to put it. That way you can immediately look up and put it where it needs to go.
