That's not really how this works. If it was a true one on one, Smith coming in on Shattenkirk and they're alone in the zone, Shattenkirk plays that completely differently.
What actually happened is that it was a 2v3 rush for LV, and Shattenkirk kept his man to the outside, assuming that the Rangers having numbers back would not allow the puck to cross the royal road.
It should be pretty easy to comprehend where the actual breakdown in this play was.
Comprehend? Ya OK lol
Really the play should've been stopped in the neutral zone but since that didn't happen #22 should've ran him through the boards near the blue line.
I don't even care if he had to take an (acceptable) penalty there.
Take Smith out.
That's his job in that situation and that's how it works.
