Let's look at Darnell Nurse and how he ranks in the league over the past 2 years for defenders with a minimum of 1500 minutes played (131 players). And see how he stacks up.
Toi/GP: 19:54 (2nd)
Corsi%: 49.80 (75)
GF%: 58.51 (63)
GF/60: 3.2 (5th)
GA/60: 3.01 (125)
XGF/60: 2.57 (9th)
XGA/60: 2.55 (121)
PP/60: 1.13(14)
PDO:1.023 (41)
Okay now let's compare him to a guy who makes 9.5 mill signed recently and has been on a BAD team
Werenski
Toi/GP: 18:25 (14)
Corsi%: 49.80 (68)
GF%: 58.51 (41)
GF/60: 3.08 (70)
GA/60: 2.02 (33)
XGF/60: 2.21 (83)
XGA/60: 2.13 (47)
PP/60: 1.16 (20)
PDO:1.003 (63)
So Zach Werenski a guy on a horrible team, with no one even in the same universe, has lesser offensive numbers although they are close... But the defensive numbers are MASSIVELY in Werenskis favor. The Oilers scored goals 5v5 at the 10th highest rate, Columbus 29th.
So Werenski is clear cut way better defensively and the fact that he can put up near the same 5v5 numbers as Nurse on a much worse offensive team?
In what world is Nurse CLOSE to that in value overall as a player
