We can pretty easily sign Granlund and Josi even at the higher end of what they would get and not have to make any moves.
This. But it does get a little dicey to get Smith signed too. I think it's going to come down to Smith vs. Granlund. If Granlund performs at a high level --- and I have a hunch he will --- then I think he'll get the priority. Smith is solid and reliable, he's a good player, but $5M or more for him if we're keeping Granlund isn't going to work.
One thing that's going to be fun and interesting (but won't affect the cap) is that there should be an influx of younger players. Tolvanen to replace Smith. Pitlick and maybe Trenin in to replace Grimaldi/Carr. And ideally all of Davies/Allard/Carrier to replace Hamhuis/Irwin/Weber.
My roster projection for the Preds for 2020-21 is only $80.007M. That's keeping Josi, Granlund, and Watson. The only significant player we lose is Smith.
That said, if there was any way we could find a taker for Turris that would be even better! Then we sign Smith too.
