Why are people blaming burns on that goal? It is pretty telling that on a 2 on 3 play burns not once looks at kopitar until he turns around and dives at the pass. That is either on boyle to give a heads up someone is not covered on the far side or get your pinching *** back into the play to cover the open man.
Burns played that play as a forward (you know his actual position) and then by the time he/someone told him about kopitar it was to late (even then burns made a great play to disrupt the play even if kopitar made a nice play to readjust himself in time to make the deke on stalock.
Boyle pinched in the offensive zone. It's the winger's job to cover him (Burns). There should be communication between the two on that play. It looks like there wasn't.
Instead of taking a look around to see where Boyle was, way behind the play, Burns focused on the puck and almost skated right at the puck carrier (bad decision)
By the time he realized Boyle was in no position to make a play on Kopitar it was too late.
Pretty basic play in which Boyle and Burns are at fault, but when it comes down to it I expect Burns to be able to recognize the situation (Boyle being caught up ice) and make a defensive play.
Maybe that's asking too much, but I think the Sharks coaching staff would expect him to make that play as well.
