15m if cap stays the same:

Vrbata 5m
Prust 2.5m
Hamhuis 4.5m
Bartkowski 1.75
Weber 1.5m

If we buyout Burrows n sign Stamkos to 7yr/9m it can be done.
The above r useless to us unless Hammer is say 3yr/3m.
We will need 4 F n 1 D only.
Baertschi Etem Granlund will slot in.
Leaves 1 F spot to be won n 2 D
- Nighthawk

As desirable as living in Vancouver is, if there's speculation Stamkos won't sign int Toronto because he doesn't want to spend his prime on a rebuilding team, I don't see that he does it for Vancouver.
