Not sure if anyone has pointed it out but Emberson and Kulak have played together the past couple games and we're absolutely caved.
Last game against Colorado they had a 29 CF% (Kulak) and 30% (Emberson) with only Drake Caggiula being worse. The xGF% was 11 and 17% respectively and a HDCF of 0%.
The night before against Utah they didn't fair any better. Emberson was a 7 CF% with Kulak at 28%. The xGF% for Emberson was an abysmal 0.47% with Kulak at 9.89%.
If Kulak isn't playing with Nurse, I'm not sure I like these two together as a pair. I think that might be part of the reason the Oilers want someone who can play both sides. They can either play with Nurse or elevate Kulak and have them play with Emberson.
I struggle with these x stats in isolation to make conclusions about individual players. As an Oiler Emberson's zone starts this season are 58.4% d-zone, 41.6% o-zone. Deployment is one critical component of game management under coaching control. Against Colorado, Emberson had second highest PK toi with 5:07 minutes, that's 26% of his total toi. Notably his short-handed zone starts this season are 93.3% d-zone, 6.7% o-zone.
Seems clear this player has coach's confidence to weight heavy defensive zone starts and to play in overwhelming PK defensive zone tilted ice. Makes sense when considering these variables that his work is in goal suppression at the cost of goal production work (xGF% and real production) better done by the Ekholm Bouchard pair matched with McDavid's elite league ice tilting in the opposition o-zone. I think advance stats have a blind spot for goal suppression players. That said Emberson came out with a point in the Colorado game. He had a couple defending wobbles notably against super elite MacKinnon but his coach was confident to roll out in critical, big PK minutes which in stopping the Ave attack was a critical part of their big win
The Utah game Emberson's game usage was carefully managed with a team defense low of 13:34 toi. Still came out of that game at +-0
A big key in this team's defense is the coaching staff managing its deployment to utilize their strengths including by comparison Bouchard's splits 73.9% o-zone, 26.1% d-zone (highest o-zone starts of his career) and Ekholm, 58.6% o-zone 41.4% d-zone. As well, Knoblauch has actively managed his middle pair deployment in game deploying Nurse and Kulak in key situations and carefully managing the ice-time of his #5=6 d-man generally around 13-14 minute toi.
I think there is a blind spot in x stats for defensive defensemen based on using xGF% as a critical measure. Important to overlay with zone start information which is active and controllable coaching function in personnel deployment in-game.
