Was just coming here to post that. "Probably" is doing a lot of work in that sentence, but I'll choose to take it at face value. I think you absolutely have to do everything you can to get Smith at center long-term, as that was part of the justification for taking him over Michkov. I don't want to be one of those teams eternally searching for a 2C in their contention window--I think 2C is the third most important position on an NHL roster.
Eklund-Celebrini-Toffoli
XXX-Smith-XXX
XXX-Wennberg-Graf
That's how I see our top-9 shaking out. Celebrini line takes shutdown matchups, Wennberg/Graf takes second matchups, Smith is sheltered a bit. Gotta hunt down some wingers this summer to make this work. But the makings of a solid top-9 are there.
