This game should be 3 - 3 with Zherdev having 3 points.
Yeah, if you are looking it at from a completely BJ's/Zherdev point of view. Hartnell hit the crossbar, Legwand fanned on an emptynetter cross ice as did Arkhipov. Oh and Hartnell had a goal disallowed. Maybe if Columbus had capitalized and Nashville didn't, then yes 3-3 is a possibility.
Of course, if there isn't an empty net on Columbus' end, they never get their second goal. Walker, realizing there was an empty net, slowed up to make a play with the puck. He was beat for icing by Nash. If Walker is trying to beat out the icing (instead of trying to feed Rem for an EN), he would have and there would have likely been no second goal by Nash.
