If the puck is in the crease, the player can be in the crease, or if the puck isn't there, the official can determine the player's presence in the crease did not impede the goalie at all (eg, half of one skate in the edge of the crease when the goalie and shot are both on the other side and no contact is made.) In Lane's case, I'm fairly sure they determined since he brought the puck into the crease, not to mention he was being contacted by the UMD defender, he did not break any rules by making contact with the goalie. Same with the UMD player, it was a loose puck in the crease with OC, he has a right to be able to go for that puck without severely impeding OC's ability to make a save. That said, OC had already put that one in the net himself by the time the UMD player got there and made any significant contact. Both calls were correct.
