My 2 cents on the Blueliners would be:
Seider-Staal (Staal can stay at home on D whilst Seider carries the play. But really, we need a better player for 1st pairing with Seider. I'm ready to dump Oesterle, drop Staal to 3rd or 4th pairing, and give Sebrango/ or McIsaac a shot at pairing up. Let's see what they can or cannot do (basically, let's get ready for 2022-23). Or maybe it's Juolevi here... but, I start him out with kid gloves before considering anything more).
Hronek-Leddy (offense only tandem but... why not?)
Lindstrom-Juolevi (I just wanna see what he's got...)
Stecher-Oesterle
