I dunno about Zadorov, I know there are plenty of folks around here who like his size, and I know folks point to the Russian factor too. But I dunno, I'm not any more interested in becoming a Russian boys club than I am in our becoming a Swedish boys club.
I know some folks immediately think "big d good", but I'd need someone to sell me on his underlying numbers.
Tanev could be a bit too old, certainly. Canucks would be in tough to try and pry a prime-aged top four RD away from a team worth it's salt though. Any team that fancies itself a playoff team probably isn't moving such a player.
I also question the wisdom of paying big to make an addition at this point, seems shortsighted a month into the season. I don't see us as a contender either, let alone a surefire playoff team. It's early, all it'd take is a catastrophic injury or two and we could be treading water.
