I made that proposal. I'm not a CBJ fan.
But for a signed Petey, it's gonna hurt. And my offer was contingent on Petey signing with CBJ beforehand.
It's going to hurt, but you're not trading that away realistically.
You're not trading a team for McDavid, as he can't win a cup in his own.
No one is trading that many top end assets for Pettersson. You need a team to win, no one player is going to get you to win.
You want to add Pettersson to your core, so you're going to move out a core peice that basically becomes redundant with the addition of Pettersson, so your number 2 centre is getting punted as Pettersson is probably knocking your number 1 centre to the 2nd spot and if you have 2 centres that are better than Pettersson, you're not trading for him.
Then you have your young players, whether 1, 2, maybe 3 seasons in the NHL, or at the top of your prospect pool and a better prospect league wide.
Picks, 1st round picks the more if you have a lesser prospect pool and potentially some other pick further in the future.
You get back Pettersson signed and probably a late pick in some year you're giving up the most picks that are all better than the ones Vancouver is sending you.
Vancouver fans want a premium and if Pettersson gets 100+ again they'll definitely want that, but no time is going to pay that amount to get him.
Vancouver will get good, or solid return, but it won't be fair. It's never a fair return for a quality player, unless they take the Florida approach in which case they might win, but I'm not sure there's going to be a player at, or close to his presumed level that will be available next off season where they could do a 1 for 1, or a trade with some additions made.
