I don't see why Maurice would break up Verhaeghe - Barkov or Huberdeau - Bennett.
Lundell and Staal then make the most sense as our 3C and 4C.
Verhaeghe - Barkov - White/Reinhart
Huberdeau - Bennett - Reinhart/White
I don't think they'd take a flier on White if they weren't intrigued with his upside. Our top 6 RW is a huge question mark, so I expect to see him tried there. Reinhart looked a lot better with Huberdeau and Bennett than with the first line, plus his face-off ability will be more important next to Bennett. If White flops, then they patch the tire until Duclair is back.
Luostarinen/Cousins/xxxx - Lundell - Hornqvist/Cousins/xxxx
Luostarinen/Cousins/xxxx - Staal - Hornqvist/Cousins/xxxx
Luostarinen probably gets moved to LW to make room for Staal to anchor the fourth line. That's okay in my opinion. He isn't going to unseat either of Bennett or Lundell, and maybe moving to the wing will tap some offensive upside that he has. Hornqvist only plays RW, so he gets locked in to one of those bottom 6 spots. That leaves a leftover spot on the bottom 6 LW and bottom 6 RW for Cousins, Lomberg, Hippo, Denisenko, and Levtchi to spar over. But it wouldn't make sense to sign Cousins to that deal and scratch him, so he probably has first crack at a spot.
