Barring the miraculous comeback I think you move two of Matthews/Marner/Nylander, and re-sign O'Rielly and Acciari.
Top 9 would still have say, Tavares/Nylander/O'Rielly/Knies/Acciari/Jarncrok. Assuming a combined 7.5 to O'Reilly/Acciari, 3.5 to Samsonov, Murray bought out, you're sitting with 31 million dollars.
Barbashev/Domi/Bertuzzi/Compher/Rodrigues, maybe a Tarasenko.. Severson on D, not to mention the returns on the two traded

Again, 31m for the 7 bolded spots. 3 of them are likely 3million combined, so 28million for 4 spots.
You're not going to make a team that's "better" on paper, but you can make one that's good enough to win and might just do a better job of it.
