That's not how things go when star forwards are traded.
For example, Jack Eichel was traded for forwards Peyton Krebs, Alex Tuch, a top 10 protected first-round pick in the 2022 NHL Draft and a second-round pick in the 2023 NHL Draft.
Alex DeBrincat was traded for a 1st, 2nd, and 3rd.
Kevin Fiala was traded for a 1st rounder and prospect Brock Faber.
Timo Meier was traded in a very large trade (The New Jersey Devils today acquired forwards Timo Meier, Timur Ibragimov, defensemen Scott Harrington, Santeri Hatakka, goaltender Zachary Emond and a fifth-round pick (originally Colorado's selection) in the 2024 NHL Draft via trade with the San Jose Sharks in exchange for New Jersey's first-round pick in the 2023 NHL Draft (conditional), defensemen Shakir Mukhamadullin and Nikita Okhotiuk, forwards Andreas Johnsson and Fabian Zetterlund, a conditional second-round selection in the 2024 NHL Draft and a seventh-round selection in 2024. San Jose will retain 50% of Meier's 2022-23 salary as part of the trade.)
But hey, if the Habs want to acquire Elias Petersson, they'll need to give up Suzuki, a 1st without protection, Justin Barron, and maybe they'll have to take on a cap dump. Throw in a second. Makes sense.
