I think time will make this more evident. Centers and defensemen win championships. Sergachev and McAvoy are exactly the type of players you want in a playoff series grind. Laine is a great power play shooter, but it’s difficult to 1) rely on the power play to score in the playoffs once players play smarter and refs put away their whistles, and 2) get your shot off once you even get the power play, because in a 7 game series, opponents study you and know your tendencies, and will take away your time and space to shoot. It’s for the same reason Ovechkin has been neutralized so well in the playoffs, and Laine is nowhere near Ovechkin’s level.
I believe Sergachev or McAvoy, even if it means minus Laine, would’ve made the Jets one of the favorites this year. I can’t say that with their current defense core.
