My apologies, I see now that I should have been more clear in my description and it wasn't quite clear about where all of this was occurring: I was referring to the defensive team losing track of a player in their own zone after, sometimes long after, the puck has entered the zone. Some players are just really, really good at "disappearing". I mentioned two of the ways that they do it: just gliding out from behind the net on the weak side (skating very lightly) is one, and hanging back on the weak side after a hard check is another. Of course, there also has to be players that can get the puck to that guy, otherwise, these techniques don't amount to much.
