I get the gist of your post, but Zub is better then every defender there except maybe Tanev and Ekholm. I think the biggest variable is also we literally don't have any defensive RD near Zub's level that can step in to replace him. That kinda makes him more valuable and worth more, especially when we factor in higher salaries. I think $5.5 for 4+ years is market value based off that
Hmmm, I don't know. Don't forget to compare to them at the moment when they signed their deal.
TJ Brodie was/is better
Dmitry Orlov is pretty damn good and better offensively
Calvin De Haan was still highly rated in 2018
Jamie Oleksiak is arguable but is also underrated
Josh Manson was thought highly in 2017
Brian Dumoulin was pretty good in 2017
Adam Larsson is very good defensively
Alexandre Edler was pretty good when he signed that
Even if Zub is better than any of them, it's marginal and not worth SEVERAL millions more. Based on these, he should not get anything over 5.0 or we're clearly overpaying. I took the salary cap rising in consideration
