Most of us (me included) assume Oshie and Duncan will play on the same line.
For fun I thought I'd shake things up a bit:
Frattin, Trupp, Oshie (If Frattin can score like Eidsness says...)
Duncan, VandeVelde, Forney (Assuming Forney's healed up and ready to go)
Malone, Watkins, Zajac (Malone and Watkins are 2 guys that can work the boards, we know Zajac can score)
Kozek, Kaip, Radke
Martens, Miller, Hextall
