I dont know if I'd move Colton unless they absolutely have to. Just look at how much better he is on the wing. Would 100% move Wood though
For next year right now we're at:
Lehky(4.5) - Mack(12.6) - Necas(6.5)
Drouin(????) - Nelson(????) - Nuke(6.125)
Colton(4.0) - Coyle(5.25) - LOC(2.5)
Kelly(0.8) - Drury(1.8) - Kivi(????)
Wood(2.5)
Toews(7.25) - Makar(9.0)
Girard(5.0) - Manson(4.5)
Lindgren(????) - Malinski(????)
Blackwood(5.25)
Wedgewood(1.5)
That group, fwiw would be $79.075M. So they'd have $16.425M in cap space and 5 guys left to sign. Kivi and Malinski combined get ~$2.5M. Leaves them with roughly $14M for the rest of the roster.
If they can move Wood out and just replace his 13F roster spot with Ivan or Prish, that would give them an additional $1.7M to work with.
Nelson probably gets $6-7M, we'll say $7M. That would leave between $7-8.5M for Drouin and Lindgren depending on whether they can move Wood. I would imagine that should be enough to get both guys honestly, though I'm not sure I want to re-sign Lindgren yet anyway. Probably depends on how well he does for us(Admittedly good so far) and what his ask would be. For something around $2.5-3M I'd take him, but if he wants $4-5M I'd probably let him walk.
All that to say I think they should have reasonable cap space to keep this entire group together next year if they wanted to. The one wildcard in all of this is Landeskog. If he returns in the playoffs, looks good and doesn't have any issues and thus expected to return for us fully next year... Then you need to move out some cap for sure. Wood goes 100%, then that's probably where you might have to look at moving Colton.
