Definitely need to get a scoring forward back if you're dealing Jake

That's not happening from a Canucks perspective

Canucks aren't sending two firsts.

That isn't the right deal from Van.
A.) The Pens want a prospect and NHL ready forward
B.) Van can't take the chance they regress next season and have a top 10 pick
C.) Van doesn't want to trade a Dman
D.) Van doesn't have the cap for that move

It is a 1st (this year), a top 3 organization prospect, and an NHL ready guy (Hoglander or Kuzmenko)

If the Canucks trade for Guentzel, it's either going to be for his expiring contract with retained salary and then they try to re-sign him themselves, or the Penguins would need to take Kuzmenko back to make the salaries work. The Canucks don't have enough cap to take on Guentzel at full cost anymore because they played the "we have cap space" card to get Zadorov for seemingly low cost.

However, Kuzmenko also has another year on his contract, and he's supposed to be a scoring forward. I could maybe see 2024 first round pick + prospect + Kuzmenko for Guentzel as a UFA, and then the Canucks sign him themselves. Once the deadline passes, the Canucks will become the team allowed to offer Guentzel 8 years on a new contract
