The key factor in any Kane deal will be his NMC. If he decides to wield it it's very possible that he could be cheaper than expected, like Giroux.
If you get Kane for futures (big IF) and get Nichuskin, Manson, and Kuemper re-signed, it's quite possible that next year's team could be just as good as this one (if not better).
Landeskog - Mackinnon - Rantanen
Nichuskin ----- Newhook --- Kane
Lehkonen --- 3C TDL rental - Compher?
4LW UFA ---- Sturm/Maltsev - O'Connor
Toews - Makar
Girard - Manson
Byram - EJ/replacement
Kuemper
Francouz
A lot has to happen for those signings to be made, and obviously Kane as well. If Chicago want to move him to kick-start their rebuild and he flexes his NMC while choosing Colorado then it could be done though. 2023 1st + JTC as a base, then add as necessary from 2024 1st/Behrens/Olausson/etc.
