I'm not sure Drury is available.
Appleton has a limited hockey IQ and defensive awareness. He's got a great motor and compete, and will give you solid effort, but he requires a ridged system to not get lost on the defensive side of the puck. I would personally prefer they find someone who reads the ice better, but he could be useful if strictly implemented in the F1 slot.
He can forecheck and dig out pucks, and will go to the net, but don't expect him to create much of the offense on his line. I feel like his numbers playing with Lowry and Niederreiter were inflated compared to what he would generate in Buffalo.
Not a terrible option, but I would aim higher.
