I remember watching Korpikari at a rookie camp a few years ago. I was impressed by his strenght and his dependable stay at home defensive style. O'Byrne was in the same camp and, at the time, I thought both had equal chances of making it with the big team.
I was very impressed with his size, skating and skills as well, but he didn't seem to like physicality. I thought he had a shot at being a Hab myself.
