Damn! Had it made you Nostradamus instead, we might have some riddle to decipher that lets us know ahead of time, ho this whole Dubois thing plays out.
Ah well...
Seriously, what are you talking about?
You said the only way we trade for PLD is with an extension in place.
If you already know that PLD will extend for $7.5 million/year, then just wait and sign him for that in 2024.
If PLD is the type to take that offer to play in his hometown now, he will do so next year.
To change his mind halfway through the year would be completely inconsistent with the premise that he would agree to a reasonable sign-and-trade. If he's going to chase money he'll do it regardless, and if he wants to come home he'll do it regardless.
I don't understand how some of you argue this from both sides. "He'll agree to a sign-and-trade for under $8 million now, but if we wait he'll chase $10 million in UFA" is a position that makes little sense. His desire to play for the Habs is well documented and he either prioritizes getting top dollar over that or he doesn't, just wait a year and you'll find out which it is.
The only reason for a team in our position to expedite this and trade for him now would be to secure his services for next year. This is useless to us as we suck and will not be competing for a playoff spot next year. Adding PLD changes nothing.
If he wanted to go to Boston and only Boston, I could see them trading for him early to get him for next year where they will actually have a use for him in their pursuit of the cup. They'd probably be trading first round picks for rentals anyway, so why not now.
But this is not the position we find ourselves in at all.
