The top-2 lines are pretty much set in stone and I would put the rest of the line-up like this:
Kobasew-Sgarbossa-Hejduk
McLeod-Mitchell-Olver
Palushaj, Bordeleau
Hejda-Barrie
Zanon-Elliott
O'Brien-Hunwick
O'Byrne
If Palushaj is not getting time on top-2 lines then we should scratch him.
People have liked McLeod's game here, but I have mostly seen badly handled pucks, missed passes and he has fumbled a lot when the puck has been passed to him.
He works well on the 4th line in an energy-role, but I feel like Koby works better up there with Sgarbossa and Hejduk.
I know this is an unrealistic scenario cause Sacco will play Mitchell in Sgarby's place and have Bordy in instead of Sgarby. (If)/when that happens then opefully he goes with:
Koby-Mitchell-Hejduk
McLeod-Olver-Bordy
The D doesn't explanations. Hejda and Barrie have worked well together, Zanon and Elliott is an okay pairing and O'Byrne has to be scratched. I guess SOB could play with Elliott and Zanon with Hunny as well.
