Sieg's and Kova were both guys who put up numbers which suggested they could be strong defensive minded d-men. Neither guy was a high pick like Mirco was either.
I also think both guys benefited from the team playing such a conservative style. We've been bagging on everyone this side of 3 guys for their lack of offense. Well some of that is by design. We went all in on being a defense first team.
Not trying to be argumentative(I know how sensitive you can be

). Just an interesting topic for discussion. Maybe moreso the latter point.
