It was definitely a set play, executed by two of the best players in the world (Lindholm and Pastrnak). But that's kinda the deal with the Leafs isn't it? A good team might get burned on a play like that, a great team shuts it down. It's Game 7 of the Stanley Cup playoffs. If you don't know where David Pastrnak is at all times then you're going to get burned eventually.
