To answer the question....
Assuming that...
kerfoot and Holl don't return
Schenn resigns at 1M
We keep Sammy for 4M
We ditch Murray somehow
Kampf resigns at 2M
ROR resigns at 5M
Bunting resigns at 5M
We're already at 85M for 20 players, and just 11 of them are forwards. We'd be at 87M after filling in the bottom 2 spots.
So this is just not feasible unless Bunting and RoR are taking massive discounts compared to what they'd get on the open market.
We are able to fit all these players under the cap because so many of them were only counting at one quarter of their hit. This is a loaded playoff lineup, not one you can take into the start of a season.
