There seems to be a short-term gap in the Top 6 at LW. Assuming we keep Kasper at 2C (I'm betting that Danielson stays in the AHL to start the year), our top six:
Left Wing - Larkin - Raymond
Debrincat - Kasper - Kane
Now at some point, MBN will be penciled in (in two years or so?), probably around the time that Kane is rolling out of the lineup for good. I'm not counting on Buch, Finnie, or Kiskinen to hit that high in ceiling (although I won't be upset if they do).
To start the year, that leaves the immediate term plugs:
Tarasenko
Soderblom
Danielson
Mazur
Longer term? - I think we have it covered if/when MBN, Danielson, and potentially how Mazur/Lombadi/Buch/Finnie etc. all shake out
But for the next two years, is there someone out there that can either plug into a top six LW role in the mold of a Bertuzzi, Oshie, etc. - or is there someone acquirable to slot into that 2C role between Cat and Kane, to let Kasper run up to the top line. That seems like a pretty big question that doesn't seem to have an immediate answer on the table
