Since the other one isn't re-opened yet ...
I like Zub with Chychrun.
Of the 3 offensive d-men I think Chychrun is the biggest gambler, therefore Zub.
It's becoming clear that Zub with anybody is great. Brannstrom has never looked better.
Personally, I really don't like juggling the defensive pairs again. Hamonic is the problem we have to solve for on defense. He's a liability every time he's out there and it's costing us. It might seem counterintuitive to stick someone as good as Chychrun with a guy like Hamonic, but I thought that pair was actually not bad, and with Hamonic "not bad" minutes are great. Chychrun is able to bring stability to a Hamonic pairing in a way that Brannstrom can't.
Sucks for Chychrun, but I think the team is stronger with Zub-Brannstrom, Sanderson-JBD, and Chychrun-Hamonic (with some shifts here or there of Chychrun-Zub to minimize Hamonic's minutes and maximize Chychrun's).
