After a blockbuster deadline

The penguins wouldn't even pick up the phone for that offer.

You need to stop trying to dump Mikheyev on the penguins. They aren't taking him.
No one is rushing it to take a guy with an almost 5 mil cap hit who has 2 years of contract left. No one.

Furthermore, the return for Guentzel alone would cost more. Willander isn't exactly an exciting prospect.

I agree with most of this, but I will say that Wallinder is an exciting prospect. However, he’s not the greatest fit for PIT, who has Letang and Karlsson eating up minutes at RD for the remainder of Sid’s career. PIT would rather have a forward prospect at Wallinder’s level who can actually contribute in a prominent role on the team very soon.

You might end up very disappointed on what Pittsburgh actually gets at the deadline. And I say this is a penguins fan.

this is exactly the point I'm making.
He's not an exciting prospect. There is no appeal for him to come to PIT. He's just another offensive defenseman prospect who can't play well in his own end to be the 3rd pairing guy they need there nor is a 3rd pairing defenseman worth trading Jake.
Lekkerimäki would have to be the return. If they aren't willing to part, oh well no trade. The penguins will get a forward prospect from one of the other 7 teams interested in Jake.

no I won't be.
People said the same thing when OTT traded out EK.
But they turned it into Norris and Stutzle.

It is really rare that a player of Jake caliber hits the trade market. Who ever makes the move is going to long term deal him. The penguins will be paid nicely for that chance.
