Above cap and minimum amount of players, plus goalies are huge a ???, they’d make or break the team. And left wing is very weak and center kinda Maybe WC, if you didn’t have Karlsson and Buff you’d probably have a lot more flexibility
Replace Byflugien, Tierney, Griess, Kuemper, Ristolainen, and Bertuzzi with Hughes, Gibson, Blackwood, Donskoi, Gusev, and Marchessault. The team will have infinitely better goaltending, and much better offensive power. Plus, it's about $1 mil under the cap. And I think you have a much better chance of finding playoff success.
