Quoting: TheGreatBigMac
Chaisson is a decent bottom six winger who works hard and plays with intensity. He was strong for the Oil in the playoffs and is great as the net front presence on the power play. MTL's power play was middling this year (17th best conversion) not sure what the issue was but Chaisson may help. The conversion rate when he was on the ice with Oil was the best in the NHL. He has size but is a bit slow and that's why we don't play him in our top 6. He is a streaky player and can get hot, he had 22 goals in 18/19. His contract is a bit high for 4LW but he has value.
I don't debate any of that, but who do you displace on the roster on the left side?
Lehk in this roster is the 4LW, and he actually has more upside, plays defensively, can skate.
So, Chiasson brings nothing to this team but physicality, and Montreal isn't designed to bring a slow skating big guy into the team, they are built around speed and tenacity, he'd almost certainly be an instant scratch as the style of player doesn't fit the philosophy of the team.
even if you roll him to the right, with hypothetically getting Virtanen, Virtanen and Armia have more upside. Tatar is your #1, and benching Byron at a higher cap hit doesn't make sense.
Unless Byron is moved, I don't see how you can chase down another 4th liner, makes no sense financially and makes no sense in the style of play
