I was listening to TSN 690 here in Montreal, and they had an interesting point about last night's OT winner by Panarin. They were arguing that the Kempny injury led directly to the Caps losing the game in OT.
Their argument is that the Caps were forced to rotate 5D all night, and on the Panarin OT winner, it's Orlov and Jerabek out there. Everything is fine, except for the fact that Orlov is playing RD instead of LD and Jerabek is playing LD instead of RD. Not a big issue normally, as both guys have played the two points during their career.
However, a left handed D covering the right side of the ice against a right handed winger is the worst possible combination.
If the winger decides to drive wide, you have to bring your stick over to your weak side to defend him, and you have very little leverage.
If the winger comes in with a lot more speed like Panarin did, he can eliminate you with a cut back move.
The correct play from Orlov would've been to be passive, let Panarin do the first move and to stop skating backwards as soon as Panarin is one stick length away. Instead, he commited to the pokecheck, failed, kept skating backwards, thinking he could drive Panarin to the outside and match his speed. Orlov realized too late that he was a step behind.
So many little details that were mishandled led directly to this goal. If Kempny is not injured, Niskanen would've been the one out there with Orlov, and he would've taken Panarin to the corner as expected.
