I like Brannstrom, but his icetime has really been heavily influenced of available roles, we don't really have any other puck movers beyond him and Chabot right now.
With Chabot back, and given Sanderson isn't going to be in the press box, the roles remaining might be a bad fit for Brannstrom's skillset. I'd still have him in my opening lineup, but it will be tough to fit him.
Chabot, Zub, Hamonic and Sanderson will be locks, that leaves 2 spots for Brannstrom, Zaitsev and Holden to compete for, not to mention JBD and Thomson. You mentioned Brannstrom playing top mins for the last 20+ games, when I checked Natural statrick, it was actually Holden leading in icetime the last 20 mins, though Brannstrom takes over if you drop it to 18 games. Point is the coach has leaned on Holden a fair bit too,
What I'd like to see is this, with the bottom two pairs getting similar icetime and maybe swapping partners depending on chemistry.
Chabot-Zub
Brannstrom-Hamonic
Sanderson-Holden
I'm skeptical that we'll scratch Zaitsev though, maybe we can trade him, idk...
