I'd think I'd do that. Mika is 31 years old, could be a potential linemate for Bedard or if nothing else help the second line and provide forward depth so opponents can't entirely key in on Bedard.
Both Mika and Jones have 5 years left on their contract but Mika is 1M less.
Maybe a change of scenery does both well, but I will admit I haven't watched much of the Rangers to know what his problem is. However, he did have 72 points in 81 games last year so I would think it's more of a coaching and culture issue given his age.
Borgen is a UFA after this year so in theory SJ is an upgrade to him for the next 5 years.
Miller is an RFA after this year and currently at a 3.8M cap hit. Are they going to be able to extend him? Keep in mind Lafrenière jumps from a 2.3M cap hit to 7.45M next season.
