I get that the window may be shorter than anticipated. Whether you want to debate if the shutting of the window is Matthews' contract, Tavares' dropoff or whatever. Personally, while the window could rest on a lot of things, for me the main piece is the Matthews contract.
Well, that is still 3 years. Thus, I think it would be a bad idea and shortsighted to go all in this year. Or to put all the eggs in one basket. I think you need to make moves based on the 3 years and even beyond... A guy like Hertl is tempting, and I'd throw in a top asset for him. But multiple top assets (Knies, Niemela, Robertson, Amirov, 2022 1st, 2023 1st) for a rental is just too much.
These assets can definitely help in 2023 and 2024. While Matthews is still here. So if you trade them in multiples for a rental. Well you lose them and the rental after 2022.
