If Nichuskin walks and there's an extra ~$6m in capspace available for the next 6-7 years, that would make it a lot more feasible to trade for and extend JT Miller...
With Nichuskin re-signing it's virtually impossible to sign a 2C for big money, but without Nichuskin re-signed the Avs will have a tonne of capspace to work with, meaning that they could acquire JT Miller at full $5.25m caphit for this season, and immediately extend him at ~$8.5m, or whatever AAV gets it done.
Allocating that money to a 2C would make a lot more sense than dropping it on a winger like Forsberg for example. And honestly as much as we like Nichuskin, if he asks for $6.5m+ that's also probably also too much to spend on another winger given how much is already being spent on Landeskog, Rantanen, and soon Lehkonen.
Miller would plug the biggest hole on the roster, and give the Avs a legit 1-2 punch down the middle again:
Landeskog - MacKinnon - Lehkonen
Newhook* ------ Miller ------- Rantanen
UFA* ------------- Meyers ------ Compher
The main issue in that scenario is the cost of acquisition. Vancouver's biggest need is RHD which Colorado now lack in their system, and thus 2023 1st + Olausson/Foudy/Behrens might not get it done. It's also doubtful whether they'd have any interest in Girard given that they already have a small puck-moving LHD in Quinn.
With that in mind, dare I say it that if the Avs want Miller then perhaps Toews would be the piece required to entice Vancouver. The trade would effectively be trading a 1C on a great contract for a 1LHD on a great contract. Vancouver probably add something or retain a bit due to the fact that Toews has two years Vs Miller's one year, and has a $1.15m lower caphit than Miller.
Avs would be of course be betting big on Byram's health and also his ability as Makar's partner starting next season. Maybe that risk is worth it to get a 1C with term while also keeping hold of Girard.
A trade like that would leave a tonne of capspace which can be used to re-sign Kuemper and Manson even at market rates, allowing you to roll out the top 6 below, which despite missing Toews is still one of the best in the league.
Byram - Makar
Girard - Manson
xxxxx -- EJ
Edit: On second thought you probably make Newhook + 1st available before Toews. Just another idea anyhow.
