He's clearly better than Marincin and Pitlick, both should not be ranked 8.0C.
Probably better than Petry and I'd rank him above MPS. So that would mean he's 3rd (if Hall and Eberle are still prospects)
I'd like to point out that both Pitlick and Marincin have dominated the Dub this year. Marincin is only six points behind Brett Connoly as a HUGE 6'4 defenceman, and Pitlick is a kid with a scary release who is playing really well with the Medicine Hat Tigers.
Just saying, I don't particularily disagree with the ranking for either of them. I feel like you've never seen either of them play, they are both physical impact players.
