It'd be Barkov...right up until the point i'm supposed to consider Contracts. At that point, for the Canucks case...i'm pretty much pigeonholed into going with Lafreniere, because even Barkov's extremely reasonable "bargain" salary would be a trick to fit in.
Having a two-way presence with that kind of size in Barkov down the middle, would open up a lot of really interesting options for the Canucks. Probably actually just ends up shifting Pettersson to the Wing though. Which is where Lafreniere would be a heck of a player to have, to really round out that Canucks winger situation, where they're always kinda at least one shy of where you'd want to be in giving top quality linemates to both of Petey and Bo. Would add some more of that physical grinding dimension that has been so valuable with JT Miller too.
