Regardless of how you feel about Brannstrom, you have to consider the following:
1. Hamonic isn't returning next season for a price we can afford.
2. Holden is likely done too.
3. We're definitely going to continue to see a pairing of Chabot - Zub
4. Even if you don't like Brannstrom, our cap situation requires us to have a cheap, experienced, defenseman, which is hard to find.
5. If Chabot, Chychrun, and Sanderson stay on the left sides, you're likely stuck playing JBD and Thomson. If you move one to the right, then you're free to keep Brannstrom to give the pairing experience.
6. If you add Kleven to the team and displace Brannstrom, you're now stuck playing two rookies on your third pairing.
7. If someone in your top-4 gets hurt, you need someone who can fill in.
I know some fans aren't convinced Brannstrom is a long-term solution, but at some point it just makes sense. The only alternative I see is to flip him for a RHD of similar experience, age, performance, and contract...but at that point, why not just try to move him to RHD?
Chabot Zub
Chychrun Sanderson
Brannstrom JBD/Thomson
Ex: Kleven/Thomson/JBD
or
Chabot Zub
Chychrun Brannstrom
Sanderson JBD/Thomson
Ex: Kleven/Thomson/JBD
or
Chabot Zub
Chychrun Sanderson
Kleven Brannstrom
Ex: Kleven/Thomson/JBD
I just don't see this as the most likely roster:
Chabot Zub
Chychrun JBD
Sanderson Thomson
Ex: Brannstrom/Kleven
Personally, I like the second option, since we can basically prepare for it this season and then simply switch out Hamonic for JBD.
