The way I look at is it depends on the kind of defenseman you want to add, they’re all equally skilled but their skills are distributed in different places
Levshunov, Parekh - pure offensive play driving defensemen, highest ceiling
Buium, Dickinson - Dependable, all around defensemen. Likely won’t be top pairing but both are good bets to be 3/4s.
Silayev, yakemchuk - true wildcards. High floors, but unknown ceilings
I’m basing a lot of this mostly on vibes. I don’t have time to watch these games. Personally I think w should get a pure offensively dynamic defenseman, cuz I don’t have faith that Simashev will be more than a 3 because of his offensive limitations
