Idk, I guess it depends on what you mean by not going to hurt us. I feel like Zaitsev is at best a 3rd pair Dman at this stage, he can do it but ideally you want someone better.
Imo, Holden playing his offside is better (with Brannstrom on the left), I think JBD had a better camp too. So putting Zaitsev there instead of one of them imo hurts us.
Add on to that his salary considerations and he's definitely hurting us, it's just the question of what hurts more, paying to dump him or keeping him around.
We've never really seen Zaitsev in a 3rd pair role. There's a huge difference between defending against the Tkachuk's of the league versus the Kelly's. What we've seen is Zaitsev defending against the Tkachuk's of the league and becoming less capable over time.
Holden is no spring chicken. He most likely shouldn't be playing 82 games at 20 minutes a night either.
How I see this is
If healthy, will play
Chabot
Zub
Sanderson
Brannstrom
Hamonic
Rotating in and out and partially dependent on how Sanderson handles pk duty
Zaitsev
Holden
JBD
Thomson
We'll be lucky to get 320 games played out of the first group. That leaves 172 games out of the bottom group and if we're really lucky, we never have to get to the point of dressing a #10 D guy.
If the objective is meaningful games in March yet still developing, then Brannstrom, Sanderson, JBD and Thomson need to play meaningful games to develop.
If that development is progressing well, it'll mean less time for all of Hamonic, Holden and Zaitsev.
