You may be right, but I think his league wide value was alot closer to burrows/hamonic then it was to Alfie/Giroux.
Hamonic and burrows were 3-4 million dollar guys in their prime while tanev is maybe 5 million in his prime. Whereas Alfie Giroux could have asked for like 8-9 million if in their prime in today's money.
So in my opinion, tanev, career wise, is closer to hamonic than Alfredsson.
But also, how many stay at home defenseman are actually very good at age 36-37-38? Once again, you may be right, but I think the odds are against that notion.
History shows there being much likelier odds that at that age, the fanbase is asking for him to be healthy scratched.
If they in fact do acquire him, I hope I'm wrong, but as it stands now, it looks absolutely silly to be targetting him as a bottom team while he has realistically only 6-12 months left as GOOD top 4 d in this league. We can revisit this prediction after the 25-26 season to see if he was still good.
My guess is he has the rest of this year and maybe 1 more year where he's a good top 4. After that he'll likely belong on the bottom pair or healthy scratched.
Just my best attempt at an educated guess. I'm no expert.
