Acciari and Schenn are guys we've got to bring back for some of that physicality.
Jack McBain is a guy on the rise in this category. I think he tops out as a 3C personally, but he's got a ton of jam, and shown offensive capability in the past.
Comtois has decent size, and uses it, but isn't in the top tier of physicality department. I think he goes UFA.
Ross Colton can play C, and often has for Tampa... he's fairly physical, but he's a RFA. Given how tight they are to the cap, they might not come to terms, and if he goes UFA, he's someone to consider.
I like Keegan Kolesar too for a bottom line role, but he's not going to be available.
Finally, I think we should consider Tyler Bertuzzi as a top six option. He's a UFA, and plays the kind of rat game we could use.
