Very true, unless they go out and acquire a cheap, rental, stop-gap 3C. Or you could try out Jarny on Sissons' spot and give Sissons the 3C. Bottom-6 like this:
Grimaldi/Tolvanen/Rinaldo - Sissons - Hartman
Jarnkrok - Bonino - Watson
At first, I was against putting Jarnkrok with Bonino and Watson, but then I remembered that Jarnkrok played great with Bonino and Hartnell last year.
I was also thinking the exact same thing about a cheap 3C, we could have lines like this:
Forsberg - Johansen - Arvidsson
Fiala - Turris - Smith (not sure if this line will come back when everybody is healthy again)
Hartman - 3c - Jarnkrok
Sissons - Bonino - Watson
Tolvanen
Looking around the league, my targets would be Chris Tierney (2 yrs left at 2.397), Kevin Hayes (1 at 5.175), or Marcus Johansson (1 at 4.583),
Other possibilities would be JG Pageau (2 yrs left at 3.1), Andreas Athanasiou (2 yrs left at 3), and Ryan Strome (2 at 3.1).
