Bellows & McLeod would be my two overwhelming favorites. Rubstov would probably be third, followed by Jones.
Not much about Kunin's game really intrigues me from what I've seen. Other than his size, there isn't anything about his game that jumps out at me and screams first round pick.
I love McLeod's speed, and he'd almost immediately give us a legitimate 3rd line centerman who can play in all situations, with 2nd line upside. The skating is there, the size is there (although he could fill out a bit) and the vision is there. The shot isn't as bad as some make it out to be, and I'll be really interested to see what he can do if he learns how to set people up more consistently with the speed.
