It was a bad night to be Sergei Kostitsyn.

We start in the Oilers zone, with the pass going to Sergei Kostitsyn (74 for Nashville) at the point. Unfortunately for Kostitsyn, the puck is bouncing, and will end up hopping over his stick.

Sam Gagner (89 for Edmonton) picks up on this immediately. I’ve had mixed feelings about Gagner’s work on the penalty kill, but one thing he does do is challenge aggressively when this kind of opportunity arises.

Gagner, who takes some flak for his skating from time to time, starts off a step behind but beats Kostitsyn cleanly to the puck. Now it’s a 2-on-2 situation; Shea Weber (6 for Nashville) is between Gagner and the net; Lennart Petrell (37 for Edmonton) is behind Gagner but clear of any of the other Predators.

And here’s Sergei Kostitsyn shrugging off the lost race with Gagner and putting his hand in the air to indicate somebody should replace him on the ice. Hilariously, at the bottom of the screen Nashville head coach Barry Trotz is pointing at Petrell, but Kostitsyn isn’t looking at him. The assistant coach on the left side of the bottom of the screen is shaking his arm vigorously and probably yelling; Kostitsyn is oblivious. The coach’s motions will get more frenetic as the play proceeds.

And now it’s a clear 2-on-1.

Weber holds back to play the shot a bit – Gagner’s in a vicious position, as he’ll have a glorious shot if Weber just plays the pass and leaves Rinne to take Gagner. Weber tries to stick check Gagner and as his stick flicks low Gagner makes the pass to Petrell. Roman Josi (59 for Nashville) at the bottom of the screen has just come on for the Predators, and can thank Kostitsyn for the minus he’s about to receive here.

Petrell blasts the puck by the goaltender.

It’s an ugly play for Nashville, and one that Kostitsyn will doubtless have trouble living down. Likely it was just a tired player trying to get to the bench, but (as he admits a little further down) even without knowing Petrell was in the picture he should have kept pressuring Gagner as the Oilers’ penalty-killer entered the Predators’ end. It’s a rarity to see such a blatant miscue by a forward in an NHL game.
