The Leafs do use the behind the net play deliberately, but it is not option #1 because a missed pass is a little extra bad. The risk is usually worth it in the right context (i.e. after the PK unit has been hemmed for a good while).

This is a good example of what NBA parlance calls '
gravity': how much a player pulls in coverage. Obviously the puck has its own gravity, and stars with and without the puck compound that effect to shape a defensive structure.
Lots to like on this play:
Tavares scoops up the puck behind the net; the PK is tired otherwise they might have contested this better. A puck retriever (Hyman/Bunting on the high end) would normally just bear down and try to jam the puck in tight and hope for the best. Elite grinders (Tavares, Crosby) use their strength and puck holding abilities to create opportunities for themselves and their linemates. Tavares' head is up the whole way looking not at the pass he's about to make, but at the future expected pass/shot and where he needs to be to support a rebound.
Unheralded on this play is Bunting, who is not the star on the ice but makes his presence known to the defense and draws a lot of attention for someone without a shooting window. He pinches low in the slot as Tavares loops and telescopes back up as the pass comes up to get himself open. He ends up providing a screen for...
Nylander with a very Nylander-esque pass: perfect reception in his hip pocket to load a shot or slip a cross-body pass, and even does a shooting weight-shift (goalies look for that). Given the way he'd been stymied all night after several good chances, everyone and their extended families expected Willy to pull the trigger here. Instead, he uses the lane Bunting opened up at the top of the PK structure to find...
Marner fields a hard pass about as cleanly as you can and makes no mistake on the empty netter with a good hard shot. Saros actually covers the puck path, but too late to make contact.
Rielly is just watching the magic; I can't believe he even wound up to one-time a theoretical Marner bump-pass.
