Ok, so sign Pinto at 1.5-2, add in a 7th D (Thomson at .863 for example) and fill in some Fwd spots with Greig (.863), Imama (.775), Smejkal (.870) and Crookshank (.838).
That's a full roster with about 4 mil in cap space. We might get another ~1 mil if Murray gets bought out.
Lets say we win the day in Arbitration, Debrincat gets 7.2.
Options become trade Debrincat for a roster player making 4-5 mil or so (that player would push off say Crookshank giving us 4.838 in space for him)
or, we could go with the fillers, and retain on Debrincat to make him more apealing, say @ 50%, we trade him at 3.6 for the acquiring team, suddenly that's a heck of an attractive rental, that you might be able to extend when the cap goes up.
the .400-1.400 in cap space we have left (depending on a Murray buyout) after retaining can be used to upgrade the bottom 6, I'd hold off till around the deadline to maximize the room.
