There is no way around the Rangers not having dead cap space next year.
They are committed at ~7.5M as is in buy outs for next year
If one wants to add S&S combined that is 10M more. (should they not be traded, retire or be bought out)
Lundqvist at 8.5M as a likely back-up, or him as a buyout at 5.5M is basically the choice.
Next year is, in my opinion, they already are at a relatively big cap disadvantage, which equates to a competitive disadvantage, does it really matter as long as they can figure out how to make the team long term better by being in that position (and a little worse position) for next season?
