Depends on your team. SJ? Absolutely. If I was say... Colorado or a more bubble team? No. Keep on building.
For a team that's already a top contender? (Say Washington, Tampa, Winnipeg) That's where it gets interesting. If I'm Washington (with most of my core pieces a little long in the tooth), I say yes. If I'm Winnipeg, with most of more core pieces on the younger side, I say no. If I'm Tampa, with them all right in their prime? ...
I honestly don't know. You're going to need to re-load your roster as the years go while you're in your window. I lean toward yes, but I think there's a solid argument against doing it.
