I don't see the logic behind blowing our wad on Markstrom. Koskinen had similar numbers and still has two years remaining. Klefbom out and a weakened PK and you're not really putting your new goalie in a position to succeed.
Trade Chiasson. Trade AA or Benning's rights if you can. Trade Russell if you can. Sign Puljujarvi. Sign a good 3C. Sign a good RD. Find value elsewhere and make depth signings. Lundquist, Howard, Dell, Kinkaid. If you save some money elsewhere, Greiss or Mrazek.
Markstrom is coming off of his Talbot 2016/17 campaign. Vancouver is doing the right thing walking away from him.
