I see this as the roster, pending any injuries, with Lehtonen, Dermott and Bogo rotating in and out of the third pairing.
This 22 man roster is slightly above the cap, but they can run with a 20 man roster on off days, papering Barabanov and Lehtonen to the minors on off days (both are waiver exempt).
Could also see a scenario where Robertson makes the team.
In that case, Boyd gets waived to the minors, and all three of Robertson, Barabanov, and Lehtonen can be papered to the minors on off days to help remain cap compliant.
