Who was Faulk defending then? There wasn't a player within 15 feet of him in any direction.
McGinn was too far out so Pesce had to charge Nordstrom. Else Nordstrom would have walked into the slot and taken his shot. It would have been a simple defensive shift except Faulk was out in no-man's land covering nobody and was unable to get back in time. I don't see any reason on that play that Faulk should be closer to the blueline than his own goal when Nordstrom has the puck below the dot.
Not that I disagree with your total point, but this seems like something the defense should always let happen. First, it's Nordstrom and I like Curtis's chances on stopping that shot. Second, even if it were someone with 1st line skill, I still like his Curtis's chances squared up against that sill vs. the backdoor tap in. Those are almost always lethal. Seems like Pesce is as much at fault on that play as anyone.
