Also, regarding the value difference,
JT Miller is an all situations player (5v5, PP1, PK1, Overtime, Shootout, 5v6 and 6v5) who plays all three forward positions and has scored 217 points in 202 games since joint vancouver in 2019.
He is coming off a 99 point season and has led the Canucks in scoring 2 of the last 3 years, coming 2nd the one year he didn’t lead.
Dumba is a offensive defenseman who can’t consistently score at a 40 points pace, has average to bad underlying numbers, plays above his head regularly, and costs 750k more.
The gap is big
Context matters here too.
And I certainly don't disagree with anything you just said about Miller.
But saying Dumba is strictly an offensive defenseman isn't true anymore. He hasn't been one since he tore his pectoral muscle 3 years ago and lost the offensive game that was turning him into a Norris caliber player at the time. He certainly hasn't been one since.
Instead, he's improved his defensive game from horrendous to league average since then to better become a more complete two-way defenseman to adapt and stay in the league who can chip in some points now and again, but is still a legitimate top 4 caliber defenseman regardless of his loss of offensive skils.
He's more akin to a Josh Morrissey or Chris Tanev, now, than a Brent Burns or Erik Karlsson. He still carries a fair amount of value and negates a large portion of what's being asked for Miller here.
No, he doesn't carry as much value as Miller. But Miller's value isn't so high that he's worth much more than what's being offered here.
Miller's value likely falls somewhere between what Debrincat and Fiala got. While both wingers, Miller isn't more valuable than Debrincat.
