Every team in the NHL has got a guy at Kulak's level or above.
If we set out some basic criteria that Kulak falls under, according to Hockey Reference, we only get 22 defensemen who:
1) Were U25 last season (Kulak is 23-111d)
2) played 20+ games last year (kulak played 21)
3) were +1.0% CFRel or better last year (Kulak was +1.7)
4) were 60% OZS or less last year (Kulak was 45%)
Player|GP|CF% rel▼|PDO|oZS%
Dougie Hamilton|81|6.9|99.6|47.7
Zach Werenski|78|6.2|101.1|55.4
Hampus Lindholm|66|5.7|100.8|47.6
Fredrik Claesson|33|5.3|100.5|57
Damon Severson|80|4.3|97|54.6
Brett Pesce|82|3.9|101.3|48.2
Brady Skjei|80|3.9|102.1|58.8
Scott Mayfield|25|3.1|99.8|55.7
Seth Jones|75|3.0|99|53.9
Connor Carrick|67|2.9|100.8|58.8
Jaccob Slavin|82|2.5|101|47.4
Troy Stecher|71|2.4|99.1|51.2
Justin Faulk|75|2.3|97.1|55.7
Aaron Ekblad|68|2.1|96.5|59.7
Martin Marincin|25|2.1|101.5|45.3
Matt Benning|62|2.0|101|56.7
Josh Morrissey|82|1.8|100.4|48.4
Brett Kulak|21|1.7|98.7|45.7
Anthony DeAngelo|39|1.5|97.3|56.5
Stephen Johns|61|1.2|96.6|45.8
Colton Parayko|81|1.2|100.7|49.6
Connor Murphy|77|1.0|98.5|41.5
Now from that list, we can further parse:
1) Parayko, Pesce, Slavin, DeAngelo, Werenski, Benning, Morrissey, Skjei, and Stecher as exempt from the 2017 expansion draft.
2) Ekblad, Jones, Faulk, Hamilton, Murphy, Johns, Severson and Lindholm as draft protection-list no-brainers.
3) One of Carrick or Marincin as protectable under a 7-3-1 by Toronto as they are only really looking at protecting Gardiner/Rielly.
4) Kulak, Mayfield, Claesson, (the other of Carrick/Marincin) as the last four players remaining.
So, no. Four teams in the NHL have got a guy at Kulak's level or above with consideration for age, for the purposes of exposure to the expansion draft. The Flames, the Islanders, the Leafs, and the Senators.
Further, you could parse Mayfield, Claesson, and Carrick out of the "final five" even further if you cared about OZS%, as all three of those guys were sitting at 55%+ compared to Kulak's 45%. I didn't bother, but maybe some consideration would be paid to how all this parsing basically leaves us with Marincin and Kulak, and Kulak is two years younger than Marincin.
Is that a whole lot of hoops to jump through to prove a point that ignores the human element of the expansion draft (rawr... needs more grit and less offensive ability to qualify as a much needed "shutdown D"!!)?
Sure. Maybe. But I think it's enough to suggest you retract the idea that every team has a Kulak they'll be exposing.
I thought earlier we needed our second round pick but now I realize it's a 2018 one that's needed.
