Going back 20 years, here is every defenseman taken in the top 5 of the draft:
Cam Barker
Jack Johnson
Erik Johnson
Thomas Hickey
Karl Alzner
Drew Doughty
Zach Bogosian
Alex Pietrangelo
Luke Schenn
Victor Hedman
Erik Gudbranson
Adam Larsson
Ryan Murray
Griffin Reinhart
Morgan Reilly
Seth Jones
Aaron Ekblad
Noah Hanifin
Olli Juolevi
Miro Heiskanen
Cale Makar
Rasmus Dahlin
Bowen Byram
Jake Sanderson
Owen Power
Luke Hughes
Simon Nemec
David Reinbacher
(28 total)
So I'd say you have roughly a 25-35% chance of drafting a top pairing or near top-pairing defenseman.
If you extend that to the top 10, these are the players that were taken 6-10:
Ladislav Smid
Boris Valabik
Brian Lee
Luc Bourdon
Oliver Ekman-Larsson
Jared Cowen
Dylan McIlrath
Dougie Hamilton
Jonas Brodin
Hampus Lindholm
Matthew Dumba
Derrick Pouliot
Jacob Trouba
Slater Koekkoek
Darnell Nurse
Rasmus Ristolainen
Haydn Fleury
Ivan Provorov
Zach Werenski
Mikhail Sergachev
Quinn Hughes
Adam Boqvist
Evan Bouchard
Moritz Seider
Philip Broberg
Jamie Drysdale
Simon Edvinsson
Brandt Clarke
David Jiricek
Kevin Korchinski
Pavel Mintyukov
Dmitriy Simashev
(32 total)
So I'd say roughly 20-30% chance of drafting a top pairing or near top-pairing defenseman.
If you extend that to the top 16 (16 being where we're likely gonna pick), these are the players that were taken 11-16:
A.J. Thelen
Marc Staal
Sasha Pokulok
Ty Wishart
Ryan McDonagh
Kevin Shattenkirk
Alex Plante
Tyler Myers
Colten Tuebert
Erik Karlsson
Ryan Ellis
Calvin de Haan
Dmitry Kulikov
Nick Leddy
Cam Fowler
Brandon Gormley
Derek Forbort
Duncan Siemens
Ryan Murphy
Jamie Oleksiak
Cody Ceci
Samuel Morin
Josh Morrissey
Ryan Pulock
Nikita Zadorov
Julius Honka
Jakub Zboril
Jake Bean
Charlie McAvoy
Jakob Chychrun
Callan Foote
Erik Brannstrom
Juuso Valimaki
Noah Dobson
Victor Soderstrom
Cam York
Kaiden Guhle
Denton Mateychuk
Tom Willander
(39 total, but keep in mind it's a range of 6 picks per draft instead of 5)
So what...a 10% chance of getting a top-pairing/close to top pairing guy?
And we'd essentially be getting the "whatever's left" of that group because we're at the tail end of it.
Of course, these are very rough estimates and it depends a bit on what players you consider top-pairing or almost top-pairing. But based on those lists, in my mind it appears as though there isn't a huge leap in quantity of solid defenseman from the top 5 to the 6-10 picks, but there is a sizable gap between the quality of said players. I'd say about 8 of the top 10 players listed in those first two groups were drafted top 5, and there are about double the amount of bonafide top pairing guys (even with 4 less players in the pool than the 6-10 group).
Something else I see, though, is that the players in the 6-10 range appear to be much safer picks. There really aren't that many "busts" or disappointments. It feels as though the top 5 has a higher ceiling/lower floor, where the 6-10 group has a lower ceiling/higher floor.
But you can clearly see the drop off from the top 10 to the 11-16 picks. There's a few unicorns in there, like Karlsson, McAvoy, McDonough, Morrissey, but for the most part it's a lot of meh or busts altogether.
So based on all that, I'd say it's worth kicking tires on trying to get into the top 10, but I don't know if I'd want to pay a huge price because even if you do get into that top 10, you're still more likely to NOT get a top pairing guy than actually get one. I'd hate to send a solid piece packing only to draft a Matt Dumba or Erik Gudbranson type.
